[Bug]: Unclear Error message with expired enterprise license

[parkerkain-8451]

What happened?

Our enterprise license expired and needed to be replaced - however the message we got when trying to investigate what was going on looked like:
Exception: You must be a LiteLLM Enterprise user to use this feature. If you have a license please set LITELLM_LICENSE in your env. If you want to obtain a license meet with us here: https://calendly.com/d/4mp-gd3-k5k/litellm-1-1-onboarding-chat.

This looks like the issue is us not setting an env variable - however we did have it set, it was just pointing to an expired license. A separate error message for no license detected versus invalid license detected would have helped speed up our debugging process immensely.
