I haven't seen anything that can do that and LG's boot-loader unlock tool only supports european G4 phones. I tried the Developer Options > Enable OEM unlock, but got a security error screen on boot when I tried flashing.

I was able to root with kingroot and install twrp which was the next best thing. You have to turn off the phone, then hold power + volume down, then release power for a second then when the lg logo appears then keep holding them both. In the factory reset menu, select (yes) perform factory reset twice and it will boot into twrp where you can flash roms and make backups.
