Given that some human at least chose the prompt (and engine and parameters) and also chose which particular pieces to select / display, it seems like if Duchamp's Fountain or found-object art is art, than so is art made with AI tools; it's not like the software is autonomous!
I do share your concerns about the current generation of software, and whether it violated people's rights in the way it was trained. That's rather a separate question from the whole "is it really art?" gatekeeping...
