Determine why VLLM will not startup with decorators, replace non-decorator deployment

[Gato]

Describe what should be investigated or refactored

When updating to confz for VLLM, an issue was identified where VLLM would not startup if the leapfrogai-api decorators were used (like @llm).

Once a root cause is identified, replace the current implementation with the decorators.
