[REQ] New python client generator which exports the api funcs as langchain tools

[abhishekmsingh]

Is your feature request related to a problem? Please describe.

I had this use case in my org where I need to provide an ai agentic chatbot over a basic crud server. Wanted to auto generate the langchain tools as they can be done using the openapi spec offered by the server easily. Think having a generator here would be useful in general as well.

I saw a thread regarding MCP server but this is specifically for tools

Describe the solution you'd like

• Introduce a new generator named python-langchain-tools.
• The PythonLangchainToolsClientCodegen class for this will extend the PythonClientCodegen and utilize it for client generation.
• The new PythonLangchainToolsClientCodegen class would just create additional files which will import the clients and export them as lang chain tools

Describe alternatives you've considered

• creating new type of generators apart from client and servers but tools are just a facade over clients so I think this would be good enougth to start with

Additional context

I have already implemented this in my local in a non platformized way using the approach mentioned above. If the community thinks this is plausible, can create a PR as well

@wing328 have raised the PR #22079 . Please have a look when you get the time. I haven't tested it e2e hence kept it as draft for now. But an early review of the overall design etc will really help.
