Nothing needs to be modified. AFAIU `main()` in Rust "returns" a Result
simply to facilitate using "question mark operator" inside `main`. But
it's just an adapter from internal API to one operating on `int`s, i.e.
`Ok()` will be converted to `0`, and an error will be converted to
another number. Current API is fine (and as a side note, the "question
mark operator" unfortunately doesn't exist in most languages. Offhand
Haskell have similar feature, Idk of any other langs).

LLM is a "large language model". The author was referring to the email
possibly being written by an artificial neural network. Although Idk
what's the ponit, but then again the OP didn't reply to this point, so
there may be something to that hypothesis.
