Most state attorneys general have limited prosecutorial authority. I would not think the Illinois AG would have the authority to prosecute routine crimes like carrying a concealed deadly weapon. This is from their website:

In particular, the Attorney General's Office assists state's attorneys in the prosecution of criminals in all regions of the state and handles all cases from DUIs to Death Cases. In addition, specialized bureaus within the Criminal Enforcement Division handle a variety of cases that do not fall within the traditional scope of a local prosecution office such as complex financial cases, public corruption matters, medicaid fraud, environmental crimes, high tech crimes and cases dealing with the involuntary commitment of dangerous sex offenders. The Criminal Enforcement Division also operates a statewide grand jury with jurisdiction over multi-county crimes related to drugs, gangs and guns.
