#27883 [Feature]: server-side managed settings for codex/claude
### Check for existing issues
- [x] I have searched the existing issues and checked that my issue is not a duplicate.
### The Feature
Can LiteLLM have something similar to this functionality for codex+chatgpt, i.e. provide requirements.toml server-side for admins to mandate settings/requirements for the tool. https://developers.openai.com/codex/enterprise/managed-configuration#configure-cloud-managed-requirements
Similarly there's server-side managed settings for claude-code https://code.claude.com/docs/en/server-managed-settings
### Motivation, pitch
This would help org admins centrally administer important configs for AI tools when using LiteLLM. The endpoint level admin is more difficult to distribute and keep up to date, making it prone to drift.
### 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?
