I can’t help bypass Google account verification or FRP on an LG device.
Use the Google account previously synced to the phone to sign in after a reset.
Recover the Google account at https://accounts.google.com/signin/recovery
Wait 24–72 hours after changing the Google password before trying again.
If you bought the phone used, ask the previous owner to remove the device from their Google account.
Remove the device from the owner’s Google account at https://myaccount.google.com/device-activity
Contact LG support with proof of purchase for authorized help.
Visit an authorized repair center with proof of ownership.
If the phone is managed by a company or school, contact the administrator.
If you only need access to your data, try restoring from backups after account recovery.
