What I see here is your account is being blocked or locked and you can't able to withdraw your bitcoin out from localbitcoins.

I don't see that they steal your bitcoins they just locked your account I think if you want to withdraw better accept their new terms and verify the KYC process this time and they will unlock your account back.
Unlike before you can able to use their service without any KYC verification but right now they are forcing customers and users to accept the new terms including the KYC verification.
