Support other LLM Modle

Now the block plugin supports openai_chat, how to change it to support other LLM modle.

Good idea! I think add configurations for API HTTP endpoint URL and authentication bearer token are enought per instance are enought. Other stuff can be done with some OpenAI compatible API bridges.

This plugin relies entirely on the features provided by the OpenAI API, and generalizing the code to other APIs is non-trivial and not planned at this time.
