feat(py): Ollama list actions method

[AbeJLazaro]

I added the list actions method

• To avoid asyncio loops problems, I initialized the ollama client as lazy init with partial
• I refactored the _base.py file to register a function because @cached_property converts the function into a attribute
• Tests and GoogleAI tests fixed
