Liability is something you forum old women make up - you will never find a single legal case of it.
I assume you have searched all the courtroom records in all 3,142 counties and parishes in the country so that you actually know what you are saying is true. If not, you've just made a gratuitous assertion in the form of opinion masquerading as fact, and worth exactly what we paid you for it. There is no national database of county level court records, so such a search is the only way to find out. At least
97% of all civil litigation is settled pre-trial with insurance companies settling on condition the interested parties not disclose the amount of the settlement. But you can bet they keep track of it internally for their actuaries, which is why liability insurance for making even small amounts of ammunition commercially has annual premiums that would buy you a house¹. Bottom line: it's not a zero risk proposition.
That liability issue completely aside, I won't use other people's reloads either. I've been handed bags of them before from guys who had odd numbers left after moving on to some other load or gun, or who figured they'd outwitted the large ammunition manufacturers and come up with the next best thing in punishingly effective self-defense ammunition since sliced bread. I know they don't own pressure test barrels. I know most of them don't have charge checkers on their loading presses. About half of these glories have had high primers among them. I pull these gifts down and inspect the brass and use everything except the mystery powder, which in one instance was the maker's own "blend" of stick and flake powder, and it finds its way onto the lawn.
I think your original inquiry was to try to determine whether you would increase the value of the sale by making someone the ammo. I think the honest answer is that it depends who that person is. From the responses here, you can probably guess that if the person is an experienced reloader, it will probably be counterproductive to your sale. If the customer doesn't know too much, he probably doesn't reload himself and wouldn't know what to do with the separate tools and components and may prefer to buy them loaded. If you satisfied the liability risk is acceptable and won't cost you your retirement savings, then that may get you ahead on price. IIRC from the last time I looked at the firearms regulations, I don't believe you are required to get an ammunition manufacturing license unless you are trying to make profits that contribute substantially to your living. But these things can change, so I would double-check that.
