I have a very stupid question, would it have anything to do with my AC not blowing out the front vents anymore? I know the answer more then likely no just figured I’d ask as I am inexperienced with vacuum lines

No, the EGR exhaust gas recirculation system has nothing to do with the HVAC vacuum
The HVAC vacuum line is black and goes to the inside of the truck near the AC accumulator
It also has a one way valve and a vacuum reservoir to make the system work
Get a service manual or use AllData at your library for location diagrams
