in case you don't know and it would be useful to you, there's tooling out there to generate license files from the Cargo.toml.
cargo lichking is an example, and I think cargo deny has similar functionality?

(I did use some tool like you mention, but my recollection is they were pretty crummy. IIRC they just did a dumb full dependency graph, so included stuff required only for platforms that I wasn't deploying for; also I think the output format was ludicrously verbose so I had to manually trim it down. This was a couple years ago, perhaps the tools have improved since then.)
