No worries having that little difference in tire size. I have 285/75/16's on mine and broke a belt in a rear tire on a trip. I wasn't towing but I did have to use the factory 265/75/16 spare for 1300 miles to get home. I found no issues with the diff when I got home and have had no issues to this day.
If you are worried then crawl under your Ex and pull the differential cover and inspect everything. If it is god seal it up, change the fluid and forget about it. If you find an issue then you fix it, tell all of us about it so we all share the learning experience, fix it and go back to enjoying the Ex.
Just my 2 cents.

Nothing will seem bad, even if you pull the cover and look at it. Only way to know is testing the LSD, go spin the tires on different surfaces and see what happens.
Another thing you might notice if the clutches are totally gone is when you let of the brake at a stop sign and give a little gas there will be a slight delay and then a slight thud (jerk forward feeling) then the truck will move forward. The slight delay and thud forward is the extra slack in the spider gears because the clutches backing the spiders are worn out. My buddies 02 did this when his clutches wore out after pulling a car trailer with one bald rear tire and one half or better thread tire. You could see it in the driveshaft in the driveway. With the truck in gear and on the brakes give it some gas and have a buddy watch how much the driveshaft turns. If it turns more than a 1/4 turn (without wheels turning at all) its a good chance the clutches are pretty well worn.
