[GuideLLM Refactor] Fix output tests

[jaredoconnell]

Summary

The output formats changed, and therefore the existing tests broke.
Keep in mind that some of the tested code may be replaced in the near future, as a new console output is in the list of things for 0.5.0.

I ran into issues with duplicate fields on the mock objects for all computed fields. Those tests are skipped. Let me know if you have a plan on how to fix this.

This PR will be in a draft state until the CSV changes are merged.

Test Plan

• Run the tests with pytest.
• Run the tox type lints.

---

• "I certify that all code in this PR is my own, except as noted below."

Use of AI

• Includes AI-assisted code completion
• Includes code generated by an AI application
• Includes AI-generated tests (NOTE: AI written tests should have a docstring that includes ## WRITTEN BY AI ##)

Here is an example of an error that I'm running into:
test_generative_benchmark_marshalling:

As you can see, computed fields are duplicated.
