Hi @logan-markewich,

I wanted to kindly ask for your help with the review of this PR. The changes introduce integration for invoking LLMs on OCI Data Science, and I’d greatly appreciate your feedback and insights.

Additionally, I’ve encountered an issue with failing tests during the CI pipeline due to the absence of the oracle-ads library, despite it being listed in the pyproject.toml file. All the tests pass locally without any problems. It seems the oracle-ads library is not being installed in the CI environment before running the tests. It looks like that poetry doesn't take into account the pyproject.toml dependencies.

When you have time, could you please take a look at this and share your thoughts on what might be causing this discrepancy? Your guidance would be incredibly helpful.

Thank you in advance for your time and support!
