I'm not sure I understand the question. You get to criminal responsibility just as was done in this case where the prosecution didn't dispute that weapons confusion was a genuine accident. They said that a person with her training and experience shouldn't have confused the two and the fact that she did was criminal.
When I heard about this case originally, I did look around, found a couple of those other taser weapon confusion cases, I think ones you referenced, and saw that they ended up as involuntary manslaughter convictions. I thought that was that, and didn't think much more about it. It seemed natural to me, as someone who has never owned or carried a taser, that intentionally drawing a gun and shooting someone by mistake automatically created criminal liability. That's because I couldn't conceive that a gun could end up in my hand without intent to draw it. I didn't bother trying to parse the culpable negligence standard.
But then I started seeing the contrary opinion, and I started thinking more carefully.
If you carry two gun-like objects, and you're under stress, it's totally possible for you to draw the gun by mistake without intent to do so. You'd be drawing and firing the less-lethal taser via muscle memory and very limited conscious perception. Whether you end up shooting someone depends on luck and training. Luck was not on Potter's side. Her department supplied her training, and it was insufficient.
She was an outlier, no doubt. Cops who suffer weapon confusion are outliers, but being an outlier is not their fault. If police departments could predict who's an outlier, then they could fire them or give them better training. They can't, and yet the existence of these outliers is still predictable, so they will continue to show up until tasers are eliminated or better training is mandated for everyone. Which goes to what I wrote in my wall-of-text post earlier. I think tasers, if they're going to require substantial ongoing training to avoid an occasional instance of weapon confusion, might be inferior to grappling instruction.

I was sympathetic to her until she took the stand. She trashed her entire defense team when she said "I didn't mean to hurt anybody!"
Her defense had built a credible case that lethal force was justified, but she destroyed it right there.
Maybe her defense screwed up by being too nuanced.
Their argument wasn't that it was a lethal force self defense case. Their argument, as I interpreted it, was something like:
1. The state's claim that use of a taser was reckless is absurd, because the situation objectively justified even more force than Potter used, and the risk of a traffic accident seems clearly more severe in the case of someone bleeding out from a gunshot than in the case of a taser where there's no gradual incapacitation over time and it stops working beyond 25 feet. Yet cops shoot people who are behind a wheel all the time when there are additional safety considerations beyond garden variety fleeing a traffic stop, which there were in this case: they didn't know if the woman in the passenger seat was the one who had a restraining order against him, and Daunte had a bench warrant on a gun charge.
2. Criminal recklessness in its theoretical construction requires four steps: First, you take an action that creates an abnormal risk. Second, you ignore the increased risk and don't mitigate it some other way. Third, a bad thing happens. Fourth, your creation of a risk and failure to mitigate it led to the bad thing happening.
The argument following from part 2 takes some contemplation, but... in a case like this, where bad thing—shooting Daunte with a gun—was already potentially legally justified, any risk Potter may have created under some legal theory proposed by the prosecution (I still don't see what she did to create any undue risk) was not an undue risk because Daunte's own actions created the risk he'd be shot, so she had no duty to mitigate that risk, so the accidental shooting wasn't criminally reckless, whatever else it might've been.

There's a lot of repetition of the standard legal argument for justified use of lethal force. Obviously she fails the subjective perception requirement. If she used that defense, she'd be guilty.
This case wasn't about a justified lethal force affirmative defense! It was a sort of a mistake-of-fact claim to gut the intentional disregard of risk element of both charges! Those two defenses are mutually exclusive! Given the bodycam footage, if she'd taken the stand and said she did intend lethal force and believed it was justified, she'd be lying. Lying about intent or subjective perception when on the stand in a homicide trial would be a good way to get a murder charge added, and get convicted on it, since you'd lose all sympathy and credibility in the eyes of the jury.
There are some special-case homicide laws that are strict liability. Mistake-of-fact wouldn't apply to those. Regular manslaughter charges are not strict liability.
Here's a weapon confusion case that was dismissed,
dismissed, from another state in 2019:

If she'd intentionally drawn the gun, a higher duty of care immediately applies, but nobody draws a gun unless they're preparing to engage in lethal force so it becomes a completely different case with no recklessness. She didn't intentionally have anything to do with the gun, so it's inappropriate to try to draw parallels to gun handling accidents, "thought it was unloaded when I pointed it and pulled the trigger" accidents. Alec Baldwin knew he was holding a real gun, capable of firing real ammo. Potter did not. She thought she was drawing a taser. Use of a taser, notwithstanding the shady prosecution witness, was justified. There's no recklessness there, because there's no conscious intent to do anything wrong or create an undue risk. Daunte was creating all the risk, and that continued through to the shooting. Daunte's actions were, in a sense, intervening acts
even after Potter drew the wrong weapon but had not yet fired. But for Daunte's continuing criminal actions, resisting lawful arrest and putting officers in danger, Potter wouldn't have been stressed or gotten tunnel vision and wouldn't have continued to believe that she had a taser in her hand, and also wouldn't have ended up pulling the trigger.
