Bruh, that's a stretch too far.
You can either say that the AI is generating the copyrighted image, in which case it is liable for the infringement, or you can say that it does in conjunction with another (like an artist under work for hire) ... in which case it's the person who provided the prompt AND the AI (the company).
I get that people like to spin legal fantasies, but the idea that, if an image is infringing, it just came from nowhere doesn't hold water.
Put more simply- are you making an argument based on any actual law, or based on what you wish to be true? There is a difference.
