We hold tool makers responsible all the time. It all depends on how the tool is meant to be used and how it's marketed.

For example, a voice cloning AI that's marketed and sold for people diagnosed with ALS to clone their voice in case they lose their ability to speak that is misused will not have any legal liability. However, if that same tool is marketed and sold to clone celebrity voices for commercials, then that company is going to have a bad time in court.
