Opt Out

If llms.txt is used to supplement perceived failures of robots.txt, it should also correct in the other direction. I'd like a way to specify a

1. Blanket opt-out of my site being used by LLMs
2. Or a price tag for the usage of my site's content, alongside instructions on how to license it.

No file, test, or entry point is named in the issue. Start by reviewing the llms.txt project description and the two existing comments; the work is done only once the opt-out or licensing behavior and its file representation are agreed and documented.
