text: Title: When using LM studio, user is prompted to enter their OpenAI API key when this value isn't needed
  Body: ### Describe the bug
  
  The change in `--local` mode now requires users to launch OI with `interpreter --api_base http://localhost:1234/v1` if they want to use LM Studio. When they run this command, they are prompted to enter their OpenAI API key. Pressing enter without typing any value allows OI to work with LM Studio successfully. However, the user should not be prompted to enter their OpenAI API key when they are using a local model.
  
  ### Reproduce
  
  1. Disable `OPENAI_API_KEY` environment variable
  2. Run `interpreter --api_base http://localhost:1234/v1`
  3. Observe OI asking for OpenAI API key
  
  ### Expected behavior
  
  Running `interpreter --api_base http://localhost:1234/v1` should work without prompting user for their OpenAI API key.
