>Everyone borrows or steals from prior art
We are products of our environment, we learned what art is by having other peoples art as reference to "what art is". So it's only natural that our own art is inspired by other peoples work. People usually do not directly steal an artstyle though and if so, they are usually called out for that. LLMs directly steal from artists works hallucinating them into a pile of stolen bullshit that roughly fits the given prompt.
