An alignment and an off-center steering wheel are two different issues (most likely)
A car can be perfectly aligned with an off-center steering wheel. The steering wheel would then need to be adjusted by the tie rods. Don't let the service center tell you they would need to pull the steering wheel off to center the steering wheel.
from a quick search, you can read how to center a steering wheel:
How to Center my Steering Wheel
the problem is a dealership or Tesla service center employs technicians who do not specialize in wheel alignments so they usually aren't done well and many of them might be ignorant on how to actually straighten a steering wheel.
I took my car to a race shop and it was done in 40 minutes - perfectly.
Understood. And thank you.
