[Feature]: Support for use_litellm_proxy as a Dynamic Parameter
Currently, using 'use_litellm_proxy=True' as a parameter causes an error.
- Call the 'completion' function with 'use_litellm_proxy=True' in the parameters.
- Observe that it results in an error.
The intended behavior is for 'use_litellm_proxy=True' to work as a dynamic parameter without causing errors. The example demonstrates how the function is called and the expected outcome.
