Oops, sorry!  But your educated guess is right.  :-)

if 'tun0' in psutil.net_if_addrs():
   # vpn is running

Brilliant!  I've used psutil for something else, but I didn't know it
did that too.  My excuse is that the version on my system was 2.2.1,
which does not do that, so I installed the newer version with pip3.
Thanks for pointing me to that.
