On Take off you need more speed to achieve lift, open split rudder will induce drag and slow down the aircraft. So no, you don't open the rudder on take off.

Another function of split rudder which we may have already observed in J36's test flight is yaw control. Below is what AI replied to me, using B-2 bomber as example:-
The B-2 bomber, being a flying wing design, lacks a traditional tail and rudder. Instead, it uses a unique system to achieve yaw control (side-to-side movement). The wingtip split rudders, also known as differential air brakes, play a crucial role here. These split rudders can open up on one side of the wing, creating drag and causing the aircraft to yaw in the desired direction. This innovative design helps maintain the stealth profile of the B-2 while ensuring precise maneuverability.
