I think your understanding of generative AI is incorrect. It's not just "logic and RNG" It is using training data (read as both copyrighted and uncopyrighted material) to come up with a model of "correctness" or "expectedness". If you then give it a pattern, (read as question or prompt) it checks its "expectedness" model for whatever should come next. If you ask it "how many cups in a pint" it will check the most common thing it has seen after that exact string of words it in its training data: 2. If you ask for a picture of something "in the style of van gogh", it will spit out something with thick paint and swirls, as those are the characteristics of the pictures in its training data that have been tagged with "Van Gogh". These responses are not brand new, they are merely a representation of the training data that would most work as a response to your request. In this case, if any of the training data is copyrighted, then attribution must be given, or at the very least permission to use this data must be given by the current copyright holder.
