Describe the bug
After installing LMCTL running the whoami command results in an error:

Error: Failed to load configuration - Config file could not be found at default location "/Users/dan/.lmctl/config.yaml" or from environment variable LMCONFIG

Although this is "as designed", it would better for the whoami command printed a user friendly message that explained how to initiate configuration for the first time.

1. Install LMCTL (ensure no ~/.lmctl directory exists on your machine)
2. Run lmctl whoami
3. See error
