🆕 New Feature ✅ Test

Changes

LitellmParams

• Makes all fields optional with total=False (TypedDict for Litellm parameters with support for both static and dynamic fields).
• Maintains type checking for predefined fields.
• Allows any additional fields through __class_getitem__.
  Preserves the original structure and purpose of the class.
  Requires no changes to existing code using LitellmParams.
  This solution gives you the flexibility to add any parameters you need while maintaining type safety for the predefined fields.

init_guardrails_v2

if isinstance(guardrail_type, str) and "." in guardrail_type:

• Split params into known and additional parameters.
• Instanciate dynamically CustomGuardrail.
• Update optional parameters while preserving existing ones.
