The Icon (DR) 4.5" system does not replace the OE brake lines. The system only includes small relocation brackets which slightly rotate the OE lower brake line brackets to which you are referring inward to provide clearance for wider tires. The 90 degree bends in the lines are present in stock form and any qualified Ford tech should know this.
The 4.5" system does not typically require bleeding of the brakes, however it is possible that a brake line may have been damaged during the installation. However this typically results in pulling to one side or the other under braking. I would suggest you take the truck back to the installer before you find yourself in the middle of a finger pointing match.
