Galvanic corrosion between dissimilar metals is going to happen in water unless you electrically insulate one member from the other. One metal acting as the anode and the other acting as the cathode. The less noble metal will be the anode and corrode.

Can you just go with a heavy ski rope type material or similar, that is ultraviolet light resistant, instead of chain? Non-conductive coating/plating on one member would work but can wear thru if there is going to be relative motion between the surfaces. An after thought...How about a piece of heavy rubber hose, or similar and durable electrical insulator, wrapped around the rebar loop and then attach the chain?
