I use the USGI kit to clean my rifle.  Through the course of many cleanings the rod and brushes have gotten to the point where they are not laser straight, and the sections of rod have a slight bell shape at the end so they stick out a bit from the rod when assembled.  Will these things dammage my rifle?  Logic says that a aluminum rid (i think the usgi rod is alum?) and brushes wont scratch chrome, but i'd like some info if possible.

Ditch the GI cleaning rod and stay away  from the sectional aluminum rods. Buy yourself a nice solid one piece cleaning rod. And to keep from bending things ensure your patches are not too tight.

USGI kit is steel.

Replace those rods.  Coated steel or brass.  One piece is best for pushing.  Best of all is to pull the rod through the bore, breech to muzzle.  No bending of rods when pulling.  The Otis kits, using the plastic coated steel cable are great for this.
Always wipe off the rod after you pull it out, you don't want to chance having that grit pressed up aginst your bore.
Aluminum rods are bad for a number of reason.  It's soft, but look up lapping.  The use of an abrasive material and a soft metal to abrade a harder one.  It also oxidizes if it's not annodised or somehow protected.  And aluminum oxide is a very hard material.  Used in coarse sharpening.

FWIW anodizing equals aluminium oxide, anodizing is just more uniform corvage of the material.

Anodizing is a means of building an aluminum oxide film on the surface of aluminum. The process consists of making the aluminum part electrically positive, or the anode, in a suitable electrolyte. The most common electrolyte is sulfuric acid. In sulfuric acid bath through hydrolysis, oxygen is released in an accelerated and uniform manner which reacts with the aluminum to form an oxide film.
