If you have left the Leaf "ON" while pumping the tire with the 12V compressor then the DC/DC converter has supplied the current from the HV pack, no power was taken from the aux battery. If the Leaf was OFF, then yes- that drains the aux battery especially if it was already weak.

I can say that while we've also had pesky tires with very slow leaks, our air compressor can run on 120 volts in the garage so filling them every few weeks (until we finally had them fixed) didn't impact the LEAF's 12 volt battery.
