Trying to build an AI brain for my store. Feasible or dumb idea?

My idea is to create some kind of “brain” for my shoe store. The plan is to connect the store, Google Analytics, Google Search Console, Google Ads and Meta Ads through their APIs, and feed all of that into an LLM along with extra context (what the store sells, who the ideal customer is, what the business goals are, etc.).

The idea is that I could basically chat with my store and get answers or recommendations.

What do you think? Does this approach make sense, or will LLMs hallucinate too much for something like this? Also afraid that the context gets way too big.
