built in trailer brake controller
I have a 2008 Chev 2500hd Duramax with a built in brake controller. My question is: Does the tow haul need to be on for the brake controller to properly operate the trailer brakes on a fifth wheel rv....

The tow/haul has absolutely no effect upon the braking system. It only controls the shift pattern of the transmission.
I just traded a 2008 Duramax/Allison (100,000 miles, mostly towing) on a 2017 similar model. My integrated brake controller did NOT work on the disc brakes (electric over hydraulics). It was an easy fix. Just had to wire in two (one would probably have done) brake magnets between the brake wire and the actuator. It then worked perfectly. All this relates only to install of disc brakes. The IBC worked perfectly with the original brake system.
Again, the tow/haul has no effect on the brake system, but it sure does help to keep the speed down on pass descents and in that way surely helps to keep from using the brakes too much.
