Has he had any exposure to Christianity? Is he completely unchurched? Hey if he is saying he’s agnostic it means he hasn’t rule out God, he isn’t sure. That’s easier to work with than saying he’s an atheist.
Is there anyone he might admire - an older teenager, a youth leader - that can come alongside him and lead him into believing? Does he admire you that way? If so, you also need someone to mentor YOU as you try to help your nephew. Someone who is a good apologist. He can point you in the right direction.
Frankly, at first I would not stress the Catholic perspective. Go for the low hanging fruit and just show him Christ’s love and mercy. Of course we want him to fall down onto the Catholic side of things

but at first, it’s better to point him to Christ and then refine it from there. Do not preach at him or lecture him in any way. Be open to any of his questions and take each one seriously. If he starts exploring other religions, don’t panic, just keep reinforcing that other religions are mere shadows of Christ’s sacrifice on the cross.
Get everyone involved that you can, everyone solidly Christian or Catholic. Get him on a bunch of prayer lists too.
He’s probably a little too young for it, but Lee Strobel has a great book called “The Case for Christ.” He was an atheist when his wife found Christ, and he needed proof that Christ was real and really was the Son of God. So he went looking, and the book is the result of that search.
