This would likely require a court case but chances are the AI law would have to offer an exception to it.

It's probably just going to fall under existing law and the owner of the AI replaces the owner of the copy that was made (so same laws, no exception). Not sure what law that is exactly, but I assume it involves royalties and the like and there's an exception for certain things, like news and maybe art.
