CI: LiteLLM often fails to start in CI (macos)

[enricorotundo]

It looks like it's quite common for LiteLLM to fail booting in CI (on darwin platform).
Here's an example failed run. There're many more faild runs in CI.
Usually it's sufficient to hit the "re-run job" to move past this issue. However, it may be a symptom of something wrong with the installation process.
