### What happened?

A bug happened! when using websearch_interception with AWS Bedrock and the /chat/completions endpoint, the agentic loop is not executed. The model correctly returns a tool_calls response with litellm_web_search, but LiteLLM does not intercept it and execute the search automatically.

The same setup works correctly when using the /v1/messages (Anthropic Messages API) endpoint.

LiteLLM should automatically intercept the litellm_web_search tool call, execute the search via the configured search provider, and return the final answer — just like it does for /v1/messages.
