No idea what pattern the lines may be in for your fridge, if they are there. I have my CO2 bottle outside of my fridge going through the side. I found exploded parts diagrams for my make and model ( a Roper) but I really stink at figuring out how everything fits together unexploded. I did see that there were lines on the sides and between the freezer and fridge compartments for my model (they are in a back and forth/ zigzag pattern but don"t always go edge to edge) but I just couldn't be sure enough of where they were exactly to trust myself not to screw something up. What I eventually did was to CAREFULLY use a screw driver to break through the interior plastic and the insulation until I was positive I wouldn't hit anything. Once I was sure I was clear I finished up by drilling a slightly too small hole (so the CO2 line has a tight fit) through the metal side of the fridge. If you can't find parts diagrams and aren't too concerned with the appearance of the inside of the fridge you could try the screwdriver "method." If you find too many lines, you could probably cover them back up with Great Stuff and sand/chisel it flat. I don't think they can be bent out of the way though. Sorta like copper tubing for an immersion chiller, they'll just kink up on you.
