I think what you meant was:
% git clone https://github.com/whateverrepo/whatevernonexistentrepo
Cloning into 'whatevernonexistentrepo'...
Username for 'https://github.com':

So it's not that Control-Z is being ignored. It's that by the time
you see the prompt for "Username for 'https://github.com': ", the
directories already exist. Try looking at
whatevernonexistentrepo/.git as soon as the prompt shows up. You'll
see that the .git directory has been greated.
Now, when you type ^Z, the git processes are stopped --- but the
objects are created already.
Username for 'https://github.com': ^Z

The 'T' means that the processes are stopped.

So what's going on is that github.com is not returning a non-existent
repo error; it's prompting for a username/password, as _if_ the
repository exists. That's presumably to prevent disclosing
information as to whether or not a private repository exists or not.
Once the authentication fails, git will remove the partially created
repro, so it's really not a problem in practice.
