What a valid file does and does not do
llms.txt is a proposal for a plain-text map of your site for assistants. No major assistant has confirmed that it reads the file, so a valid file does not promise citations. It is cheap to publish and a good test of whether your own site map is in order; the crawler access check matters more.
