Update my LLM set-up after 0.60.0 update

in agents, we have to pass llm= and i used to pass langchain’s models. But with new changes how do i pass? beause i cant set environment variable to us-east-1 for region since us-east-2 is required for application to run, where as bedrock is only in us-east-1, earlier i used to pass region name in langchian’s model

Yes, please check the llm section of the docs
