I think the most acheivable way of having some verification of AI images is simply for the AI generators to store finger prints of every image they generate. That way if you ever want to know you can go back to Meta or whoever and say "Hey, here's this image, do you think it came from you". There's already technology for that sort of thing in the world (content ID from youtube, CSAM detection etc.).
It's obviously not perfect, but could help and doesn't have the enormous side effects of trying to lock down all image generation.
