I think there is threshold beyond which more intelligence for LLMs is not more utility for a project. My hypothesis is that a personalized LLM, one that learns from the way in which you live, your ups and downs, what you consider important, and everything else, that personalized LLM could really help produce an unique interface in which the symbiosis creates the best result.

Also, if such LLM use can really produce better projects and if it is not easily transferable, then there is a strong incentive for you to explore that hypothesis: Designing such a symbiotic system could keep your career alive. Caveat: Not any LLM was used here.
