It's a risk for Bob, I think he should be the one judging whether it's worth it or not, since he'd probably get in trouble over this. What I take away from this is that it'd be helpful if the tool clearly warned him of this risk.

Other than that, I'm sceptical for using LLMs for lots of things, but this I find cool. In my consulting work (and even before as a CTO), I usually train PMs, CEOs, really anyone who didn't make it up a tree by the count of 3 some basic code/tech literacy.

Imagine if Bob used this tool to learn about SQL and the data scheme. Now he got a glimpse of the inherent complexities, knows better when and how to ask for help, can have more trust in and better conversations with those engineers. Sounds naive probably, but I've usually seen these results from my (manual) efforts.

Of course that only works if the tool exposes the generated SQL in some fashion, it looks like it can but I might be wrong. If it's like you say and it's just natural language in, data out, I'd say that's more likely to do harm than good :)

Edit: Took a minute to look at the code, and it looks like there's no API to generate SQL from a question, just the "question" API that generates SQL on the fly and returns the data. I really think there'd be a lot of potential in at least returning the actual SQL query along with the data. Hope I didn´t miss something!
