It doesn't increase when I accelerate it actually goes away it mainly does it driving in the really low rpms like when you let off the gas at 25-30

I know you said it's not the belt, but do not know how you came to that conclusion? Did you take the belt off and run the engine? I had a funny squeak as well and thought it was a problem rocker. Did the same thing you're describing. Found out it was the #1 primary on my LT's that was making contact with the brake line heat shielding.

I have an intermittant annoying squeak and its the AC compressor pulley or maybe its bearing. I have to spray it from time to time with WD40 and then its quiet for months or until it gets wet.
Idler pulley is also a usual suspect. You should pull the belt to further diagnose.
