Is this OK? Should I be concerned about the AWD drivetrain issues. Or is this negligible?

I’ve never gotten a clear answer on this. My 2012 Limited manual doesn’t say anything about it.
Minimally, change 2 tires (2 front or 2 rear) and never cross them to front+rear.
What is your new tire tread depth? 15/32? Assuming so, you would have (15-9)*2/32” or 12/32” or 3/8” less diameter on the old tire if you only replaced one tire. The new tire would rotate fewer times per mile as compared to the one at 9/32” tread, which is what causes stress on the diff.
Based on that, I do NOT advocate changing just one tire.
The other advice I got - change all 4 and sell the other 3.
