Funny enough, Saul and I recently hacked on getting visidata's Ibis integration updated, so you can use visidata for poking around databases of any size, really. You might like that, but also visidata has non-ibis support for SQLite I believe.
This is super interesting. I do have a GitHub issue for LLM-powered data entry: "Add a landscaping project to do the backyard. Still ideating, thinking a budget of $40k."
