Lost access to Google account and license. Is recovery of license possible?

ost access to Google account and License. Is recovery of the license possible? I no longer have a Google account, and I accidently bricked my phone a few days ago. I unbricked it with a factory reset. I am unable to use Litchi because I don’t have my license (I downloaded the apk of a older version of Litchi because my phone suffers from the 100% database download bug). And I am unable to purchase a new license because I do not have Google Play. Please help!
Thanks in advance!

P.S I use Litchi since my NUU X6 Plus won’t run 64 bit apps, therefore it can’t run DJI Fly.

isn’t this the same as you asked here
