This shouldn't be enforced through technology but the law.
LLM and other "genAI" (really "generative machine statistics") algorithms just take other people's work, mix it so that any individual training input is unrecognizable and resell it back to them. If there is any benefit to society from LLM and other A"I" algorithms, then most of the work _by orders of magnitude_ was done by the people whose data is being stolen and trained on.
If you train on copyrighted data, the model and its output should be copyrighted under the same license. It's plagiarism and it should be copyright infringement.
