After doing that, it's probably wise to make a completely new wallet as the Bitcoin wallet has had the private seed exposed by entering it.
I'd rather suggest the OP to create a new Ledger seed, move all his funds to the new addresses and then start the recovery process of his LTC.
Don't risk all the funds you're holding on Ledger to find your LTC. Your PC might be infected or, even if it's not, entering the seed anywhere except on your Ledger implies a big risk.
After safely moving your funds, go to a website like the one included in the post above me and find your Bitcoin private keys off your Ledger Nano S seed. You have to import them into a wallet after you've found them, but follow the other posts - here I'm not an expert. What I'm willing to say is just make sure your other funds are 100% safe before entering the seed or a private key anywhere.
