Is llms.txt a real standard?

It is a convention, not a W3C standard, and several assistants read it.

Will it break my SEO?

No. It sits alongside robots.txt and changes nothing for search crawlers.

How often should I regenerate?

When your page list changes materially. Quarterly is plenty for most sites.
