In the short therm, I think it's very likely that companies (including smaller companies) integrating LLM's in their products want to locally run an open source LLM instead of relying on an external service, because it gives more independence and control. Also, technical enthousiasts will run LLM's locally, like with image generation models. In the long term, when smartphones are faster and open source LLM's are better (including more efficient), I can imagine LLM's running locally on smartphones. 'self-hosting', which I would define as hosting by individuals for own use or others based on social structures (friends/family/communities), like the hosting of internet forums, is quite small and it seems to shrink. So it seems unlikely that that form of hosting will become relevant for LLMs.
