If the wallet really encrypted, you won't able to find private key/master private key (xprv) on the raw file.
There are several wallet.dat format, but the one i know use PBKDF2 where PBKDF2 private key used to encrypt master private key & PBKDF2 private key is encrypted with user's password.

There are few tools to brute-force Bitcoin core (such as https://github.com/glv2/bruteforce-wallet), but i've no idea if it's works with broken/corrupt wallet.
Personally i'd recommend professional recovery services (such as https://walletrecoveryservices.com/) in this case.

It is not HD wallet. Addresses started with "1". Keys encrypted independently or in some big chunk? This PBKDF2 key stored in some fixed place? It is possible to find them manually?
