It does use LLMs with the precision controller - which determines the degree to which ontologies are applied to not-semantic-web-data. This is done with LLMs as translation tools if the precision controller is adjusted with a low precision degree (ergo more fuzziness, ergo more LLMs).
But yeah, it's basically meant as a contra-approach to ChatGPT-like apps, giving users back control. And because rule-based systems have always failed in the past, LLMs are used if the user wants to make the app more fuzzy and access more data this way.
