They probably aren't doing that. Studying the production methods and WIPs is more useful for a human. (ML models basically guess how to make images until they produce one that "looks like" something you show it.)

They do sometimes, or at least they used to. I have some (very limited) visual art training, and one of the things I/we did in class was manually mash up already existing works. In my case I smushed the Persistence of Memory and the Arnolfini portrait. It was pretty clear copycat; the work was divided into squares and I poorly replicated the Arnolfini Portrait from square to square.
