There are lots of things that are not simple reproductions that are not fair use.
If I take ten of your copywritten photographs and stack them on top of each other in Photoshop with transparency, the output is not a simple reproduction of your work. If I sold that for commercial purposes you would be upset with me and likely have a copyright case.
That's an obvious example, but my point is there aren't super clean-cut definitions for these things, and it's not settled case law yet which side current AI training and content generation falls under.
There is tons of human made art in contemporary art museums that is copywritten stuff re-arranged.
Most famously might be Andy Warhol's Campbell's Soup cans. You can find plenty more though. Product labels, magazine covers, pasted together as "art" even thought each part is copywritten.
