I had new shock mounts/bushings replaced about a week ago. Mechanic said that he "flushed and refilled" the hydraulic fluid but that I'd have to handle re-adjusting ride height.

It's quite a bit lower than previous to the work.

Is it possible that it requires bleeding air out using the bleed screw?

Would I do the following:
loosen the screws on the turnbuckle on the torsion bar, then
insert a pin or small screwdriver through the lever and into the hole on the side of the controller body, then
tighten the screws on the turnbuckle.

or do I shorten or lengthen the lever?
how do I pop off the lever on either side?
