Yes. The past two companies I've been at have self-hosted enterprise LLMs running on their own servers and connected to internal documentation. There is also Azure Cloud for Gov and other similar privacy-first ways of doing this.
But also, running LLMs locally is easy. I don't know what goes into hosting them, as a service for your org, but just getting an LLM running locally is a straightforward 30-minute task.
