#28145 [Feature]: Optional return of raw_response for search tools
### Check for existing issues
- [x] I have searched the existing issues and checked that my issue is not a duplicate.
### The Feature
Based on an optional request header would be nice to disable the search tool response transformation and send back the original response (raw_response) back to the client.
### Motivation, pitch
In case of Tavily the current implementation removes meaningful parts from the response of Tavily API. https://docs.tavily.com/documentation/api-reference/endpoint/search
It would be nice to have support with a flag per request that forces LiteLLM Proxy to act as a proxy.
### What part of LiteLLM is this about?
Proxy
### LiteLLM is hiring a founding backend engineer, are you interested in joining us and shipping to all our users?
Yes
