I thought this would reduce the amount of torque since the servo arm force vector is no longer 90 degrees to the pushrod.
Yes, but if you do the maths with sins and cosins etc, you will see that you have to be more than about 20 degrees to get any kind of measurable change, and even more degrees to get a noticable difference.
You have bigger angles due to the section of the wing than you will get going to a different hole on the control arm. It is not an issue.
