Custom ReAct with tool and llm

ToolとLLMに聞くのをうまく組み合わせるやり方が分からなかったので、Toolで直接llmに聞くというのを作った。

    tools = [
        Tool(
            name="GetBirthplace",
            func=get_birthplace,
            description="Get birthplace of a person.",
        ),
        Tool(
            name="Llm",
            func=llm,
            description="Use this tool to ask general questions"
        ),
    ]
