refactor: remove unnecessary logging from LiteLLM initialization

- Removed logging of model configuration to avoid redundancy.

chore: remove OpenAI key management module

- Deleted the `openai_key_pool.py` file and related imports.
- Removed associated test cases and references.

This change simplifies the codebase by eliminating unused functionality.

chore: update contact email in core utilities

- Changed contact email from `[email protected]` to `[email protected]`.

chore: reorganize imports in utility module

- Removed unused imports from `__init__.py`.
- Ensured only necessary modules are exposed in the `__all__` list.

This change improves code readability and maintainability.
