Your LPS has multiple ground rods deep into the earth safely dissipating the charge.
So your experience is evidence the LPS protected the home. Similar to an umbrella protecting you from the rain.

I believe this is exactly what happened. The cable line is a common path for an induced power surge to enter your home. It happens often. There is a cable surge protector that you can get on Amazon which will help with this problem. You install it where the cable line enters your home. If you have fiber internet, no need to worry about this problem.
