- Updated `conftest.py` to set fake API keys only if real ones are not available, enhancing test flexibility.
- Refactored the `mock_llm_calls` fixture to conditionally mock LLM calls based on the use of real APIs, improving test isolation and reliability.
- Ensured that when real APIs are used, the mocks return empty values to allow tests to run without interference.
These changes enhance the robustness of the testing framework and ensure better handling of API dependencies.
