Tire pressure sensor(!) ??

Is it normal for the tire pressure sensor to come on after installing 295 70 17 trail grapplers on 17 pro comp 7069???? The sensor light came on 2 days after install tire pressure is at 34psi's

Yes.
When you break a tire down for dismounting, you bring the perssure down to 0psi. It may take a few miles to reset. If it doesn't take it back to the shop you had install them.

Or buy an AEV-Procal and disable it.

If the light stays on and they did put the sensors in and you are up at the correct pressure then either a sensor has failed or one of the transmitters has failed. At that point buy a ProCal or Superchips and be done with the light.

FWIW, I run stock sensors and a superchips but I still have my TPMS turned on, I just dropped the alert pressure to 32 instead of 35psi.

The system does know that the tires hit 0psi, unless you changed them something like 50ft away from the vehicle. Remember it uses Radio Frequency to transmit pressure. Its is normal for the light to come on after changing tires. Two days later is not.

Did you tell your tire shop to break down the TPMS and carry them over to your new rims? If you didn't explicitly ask for this, odds are they just installed regular valve stems in your new rims, and that is why the TPMS light is on.

Just buy a ProCal and be done with that horrible TPMS
