Removing Depricated OpenAI API endpoint

[Garcluca]

line 120 in /agents/agent_builder/create.py uses an openai endpoint that appears to be deprecated. I was not able to find any documentation about this, but it caused an unhelpful error message and looks to be unused.

I am currently using bash with windows subsystem for linux, and encountered the issue using the following command

python3 -m agents.tool_maker.unit_manager

I discovered this on a spinoff project that this project inspired and have tested it with the main repository. commenting it out appears to fix the issue without affecting performance.

Error message:

.local/lib/python3.10/site-packages/openai/_base_client.py", line 980, in _request
    raise self._make_status_error_from_response(err.response) from None

In the following block, the check for whether a "retrieval" tool type exists may fail if existing_agent.tools is None or empty. You need to ensure the list is valid before performing this check.
