2 errors that remain from mypy check -

• X | Y syntax for unions requires Python 3.10 - Backwards compatibility will require changing the codebase to use the Union type instead of the | operator
• Cannot find implementation or library stub for module named "<module>" - Occurs for the langchain, openai, and tenacity libraries. This is not shown when the --ignore-missing-imports arg is used with mypy. A permanent solution would be to generate stub files for these libraries.
