feat(guardrails): optional skip system message in unified guardrail inputs (#25481)

* feat(guardrails): optional skip system message in unified guardrail inputs

Made-with: Cursor

* feat(dashboard): skip_system_message_in_guardrail in guardrail UI

Add a tri-state control (inherit / yes / no) when creating or editing
guardrails so admins can set litellm_params.skip_system_message_in_guardrail
without YAML. Table edit merges existing litellm_params before PUT to avoid
wiping content-filter and other provider fields.

Document the dashboard flow in the guardrails quick start with a screenshot.

Made-with: Cursor

* fix(guardrails): type structured_messages as AllMessageValues for mypy

Use AllMessageValues in openai_messages_without_system and cast adapter
request messages so GenericGuardrailAPIInputs matches TypedDict.

Made-with: Cursor

- A list of the above values to run multiple modes, e.g. `mode: [pre_call, post_call]`
### Skip system messages in guardrail evaluation
You can stop **unified** guardrails from scanning `role: system` content while still sending the full `messages` list to the model.
**Global** — in `litellm_settings`:
```yaml
litellm_settings:
skip_system_message_in_guardrail: true
```
**Per guardrail** — under that guardrails `litellm_params`: set `skip_system_message_in_guardrail: true` or `false`. If omitted, the global `litellm_settings` value is used; per-guardrail `false` forces system messages to be included even when the global flag is `true`.
**Via LiteLLM UI** — when **creating** or **editing** a guardrail in the LiteLLM Admin Dashboard, set **Skip system messages in guardrail** (under Basic Info on create, or in the edit / guardrail settings flows):
| UI option | Effect |
| ------------------------------------- | -------------------------------------------------------------------------------------- |
| **Use global default** | Uses `litellm_settings.skip_system_message_in_guardrail` from your proxy config |
| **Yes — exclude from guardrail scan** | Sets per-guardrail `skip_system_message_in_guardrail: true` |
| **No — always include in scan** | Sets per-guardrail `skip_system_message_in_guardrail: false` (overrides a global skip) |
<Image
img={require('../../../img/skip_system_message_guardrail_ui.png')}
alt="Create guardrail: Skip system messages in guardrail dropdown with Use global default, Yes exclude from guardrail scan, and No always include in scan"
style={{ width: '100%', maxWidth: '900px', height: 'auto' }}
/>
**Where this applies:** Only the **unified** guardrail path (providers that implement `apply_guardrail` and run through LiteLLMs message translation layer) on **OpenAI Chat Completions** (`/v1/chat/completions`) and **Anthropic Messages** (`/v1/messages`). Examples include Presidio, Bedrock guardrails, `litellm_content_filter`, OpenAI Moderation, Generic Guardrail API, and custom code guardrails that define `apply_guardrail`.
**Where this does *not* apply:** Guardrails that run only via direct hooks on the raw request (e.g. Lakera v2, Aporia, DynamoAI, Javelin, Lasso, Pangea, Model Armor, Azure Content Safety hooks, Guardrails AI, AIM, tool permission, MCP security). It also does not apply to other routes until those endpoints use the same translation layer (e.g. Responses API, embeddings, speech).
### Load Balancing Guardrails
Need to distribute guardrail requests across multiple accounts or regions? See [Guardrail Load Balancing](./guardrail_load_balancing.md) for details on:
- Load balancing across multiple AWS Bedrock accounts (useful for rate limit management)
- Weighted distribution across guardrail instances
- Multi-region guardrail deployments
