Is not replacing the O2 sensor OK?
I am about 1000 miles away from home and got a check engine light. It is the O2 sensor Bank1 Sensor 1. Am I doing any engine damage by not replacing the sensor until I get home?

It is against the firewall, away from air flow.
Damage to the catalytic converter by overheating is sure to occur in a thousand miles. It could possibly catch fire. If at all possible have the sensor replaced or the vehicle towed.
A toyota dealer may be a closer option with the correct part available. Stay away from a non-Denso part. (not toyota)
The O2 sensor is probably open or infinity on a meter, burnt from overheating. The high ohm value now on this sensor is telling the ECM to lean the bank of three cylinders, contributing to the overheating.
A self-destructive cycle.

What was the actual code?
It might just be a split second reading showing a lean condition. The P0171 is the one I am thinking you got and it could also have been a dirty MAF that can be cleaned.
Did you attempt to reset the light after you got the code?
Otherwise, you can pull the EFI fuse in the fusebox for a few second (with the key out of the ignition when you do this) and that will reset it.
From what I have read, the RX has a default condition, which means the vehicle won't run as efficiently when this occurs (an actual O2 sensor issue).
