Help Please! Sagging Front end, can't adjust Ride Height at all.

Let me preface this by saying I don't have any drag race experience. So these these thoughts are coming from someone not in their lane.
The op stated that the car puts the front tires in the air on launch. When the front tires are in the air, my thought is at this time they have little influence on the direction of the car. Things like front end alignment, loose or worn front end components would just be along for the ride until the tires touch back down.
The rear tires would be what are steering the car. I think the traction difference between the lr and rr tires is what primarily would steer the car right or left.
I think if you have a car that launches straight and then lower the ride height somewhere on one corner of the car ( which will affect the ride heights on the other three corners) it will affect the weight distribution on all four tires. This in turn changes the tire load between lr and rr tire and tire load affects traction which affects steer at the back of the car.
Changing from a 150 pound driver to a 250 pound driver also changes the tire load between the lr and rr tires if the driver is positioned on the left side of the car.
