Describe the solution you'd like

Add Crusoe to the LLM providers list in docs/edge/en/concepts/llms.mdx, following the same accordion format as the other LiteLLM-backed providers (Fireworks AI, Perplexity AI, etc.).

Crusoe is an existing LiteLLM provider (BerriAI/litellm#23195, merged), so LLM(model="crusoe/<model>") already works in CrewAI today via the crewai[litellm] extra — it just isn't documented. Crusoe provides OpenAI-compatible managed inference for leading open-weight models (Llama 3.3, DeepSeek, Qwen3, Kimi K2, and more) on renewable-powered GPU infrastructure.

This is a docs-only change; no code is touched.

Describe alternatives you've considered

Leaving it undocumented — but users have no way to discover that the provider already works, and every other LiteLLM-backed provider of comparable size has an entry on that page.

Additional context

PR #6530 already implements this and is ready for review. Opening this issue as the tracking issue @Vidit-Ostwal requested there on 2026-09-04, and to satisfy the first-time-contributor linked-issue requirement.

Willingness to Contribute

Yes, I'd be happy to submit a pull request (already open: #6530)

Start with docs/edge/en/concepts/llms.mdx and review the accordion entries for LiteLLM-backed providers such as Fireworks AI and Perplexity AI. Confirm the existing Crusoe provider details and match that format; done means Crusoe appears in the LLM providers list with its supported model usage documented. PR #6530 already implements this work.
