Refactor verbosity handling in OllamaAPI

- Removed the verbose logging feature from the OllamaAPI class and related classes.
- Updated logging statements to use debug level instead of info for model requests and responses.
- Cleaned up related test cases to reflect the removal of verbosity settings.
