Yes, no problem at all, but rather a standard correct configuration.
Multiple Sitemaps — Normal
the robots.txt is standardized to allow you to declare multiple Sitemap: lines. Google/Naver reads each sitemap independently. The core rule is "The same URL must not be duplicated in two sitemaps" and we are neatly separated: Root sitemap.php → lualocca url only (/en/... etc) ruabar/sitemap.php → Ruaba URL only (/ruabar/en/... etc) It is a formal pattern used to run multiple sites under one domain. If you register both in Search Console, you can see the collection status of each sitemap separately, which is better for management. multiple llms — normal
Root llms.php = About Ruaroka, ruabar/llms.php = About Ruava. Since the AI crawler reads by path, there is no collision concept per se, and it is better to accurately describe each site. It's like having two shops (Luaroka/Luava) in one building (suasubin.com), each with their own signboard. The robots.txt at the entrance of the building is the clearest form for a search engine because it says, “There are two signage signs here.”
