Description

When using OpenAIChatModel, environment variables for proxy are ignored.

// OpenAI model setup
const model = new OpenAIChatModel({
  apiKey: process.env.AZURE_OPENAI_API_KEY!,
  endpoint: process.env.AZURE_OPENAI_ENDPOINT!,
  apiVersion: process.env.AZURE_OPENAI_API_VERSION!,
  model: process.env.AZURE_OPENAI_DEPLOYMENT_NAME!,
 
});

The connection to model is internally handled by @teams.openai package which doesn't use environment proxy

Reproduction Steps

1.Set https_proxy, proxy and no_proxy env variables
2.Run sample chat app with OpenAIChatModel
3.The connection is done without proxy
