Fix Vertex AI API error: "tools[0].tool_type: one_of 'tool_type' has more than one initialized field" The Vertex AI API requires each Tool object to contain exactly one type of tool (e.g., FunctionDeclaration, GoogleSearch, CodeExecution). Previously, all tool types were combined into a single Tool object, causing INVALID_ARGUMENT errors when using multiple tools simultaneously. This change creates separate Tool objects for each tool type: - Function declarations in one Tool - Google Search in its own Tool - Code Execution in its own Tool - etc. Ref: https://cloud.google.com/vertex-ai/generative-ai/docs/reference/rest/v1beta1/Tool 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com> |

Testing for litellm/
This directory 1:1 maps the the litellm/ directory, and can only contain mocked tests.
The point of this is to:
- Increase test coverage of
litellm/ - Make it easy for contributors to add tests for the
litellm/package and easily run tests without needing LLM API keys.
