If it's been a few days, I doubt the thief would have left the coins sitting on his Localbitcoins account to this very day. He might have already tumbled and laundered your coins long before PayPal limited your account.

I have been repeating myself here about PayPal's reversibility risks to a point where I probably sound like a broken radio or a retarded parrot but I do it in the hope it will at least save one from being victimized by a PayPal chargeback scammer. Your experience is an example of the kind of scam you see on an almost daily basis in the currency exchange, loans and goods sections. The throwaway accounts keep coming, a never ending cycle of creating accounts, scamming, discarding accounts and creating more.

Yes, you can open a ticket but I doubt you will get any coins back.... unless the thief's LBC account was locked after the transaction or placed on forced holiday. This happens when users trigger the site's automated fraud detection system which then refers the account for manual review or identity verification. If you're lucky, the thief's coins might still be on his account. Open a ticket but don't get too excited. Expecting a loss will help you cope with the situation better if it turns out the coins are gone.

I would still recommend that you report the matter to Localbitcoins. Banning and suspending the thief's account will at least help prevent further misuse of that account.
