Pre and Post Thermostat Temperatures
I will get an IR gun at the first of the month and tackle all of the issues we have identified.
Does anyone have an Autel AP200? THat is what I have for an analyzer.. The live mode show two temps not sure why? They are both reading the same temps not sure but it makes me think it is not circulating

Engine Temps Cycling
The temps read $7E1 and the other reads $7E2 and monitoring the the temps for a two hour drive both temps match the most I have seen difference is 4 degrees.

The temps at idle just continued to increase all the way up to 250. The temp gauge starts to move at 248. This is just sitting there. I seen no cycling of temps then though.

You're probably not going to like this answer, but I would start by replacing the MAP sensor as Fly advised in post #24. It may not be directly related to the overheating during idling, but it’s something you can probably do yourself right now at minimal cost. Then reset the OBD codes.
At that point, after all your OBD codes have cleared, if you’re still overheating at idle then the fan and/or thermostat are the most likely culprits. At 130K miles, both are candidates for replacement anyway.
Back to the MAP sensor: In the Youtube video shown below, the guy replaces his MAP sensor during the first few minutes of the video. His Volvo has a little more working room than your LR2, but if you have a long slender arm you may be able to do the same as he did.
Additionally, I posted a few months ago on how to remove the MAP sensor once you have your hand on it:
