If those tools are writing the code then in general I do expect that to be included in the PR! Through my whole career I've seen PRs where people noted that code that was generated (people have been generating code since long before LLMs). It's useful context unless you've gone over the generated code and understand it and it is the same quality as if you wrote it yourself (which in my experience is the case where it's obvious boilerplate or the generated section is small).
Needing to flag nontrivial code as generated was standard practice for my whole career.
