soft 404 on a machine file

A platform that answers every unknown path with its homepage answers /llms.txt and /sitemap.xml that way too, at HTTP 200. A nonexistent-path control fetched in the same scan identifies the catch-all page, and any machine file that matches it is recorded as absent rather than present or broken.
