feat: address PR review feedback with improved dependency constraints and tests

- Add upper bound to litellm constraint: litellm>=1.72.0,<2.0.0
- Enhance test suite with parameterized testing across multiple model types
- Add version constraint validation test to ensure proper bounds
- Improve test documentation with detailed explanations
- Add error handling enhancements as suggested in review

Addresses feedback from PR review by joaomdmoura in #3006
