### Check for existing issues

- [x] I have searched the existing issues and checked that my issue is not a duplicate.

### What happened?

Starting with version v1.92.0, LiteLLM tries to download the Prisma binaries and fails if it cannot reach the internet. In many corporate networks, egress is limited and thus, LiteLLM cannot be used.

### Steps to Reproduce

1. Run migrations with egress disabled 2. Container will be stuck retrying to fetch the prisma binaries
