It's for a friend who think he has the passphrase and wants to see if the addresses have Bitcoin!

If your friend mined bitcoin in 2014, but now has a wallet passphrase, he can unlock the wallet file and access his bitcoin.

If not, he need an unenrypted wallet file to access his bitcoin.

You can not brute force Bitcoin private key from Bitcoin public addresses that has balance, because if you can do it, many other people would have done it before you.

Private key > Public Key > Public address, it's always one-way process, not way to do backwards like Public address > Pubic Key > Private key.

Ad I mentioned he does not have a wallet file.
He thinks he knows the passphrase or password use to create the address at command line.

I do not know what process was back than.

I am not trying to brute force anything. As I explain we have a "known" passphrase / password and want to use the script to create the pkey which leads to an address to see if it exists and contains coins.
The script above takes some passphrase or passowrd, creates pkey, than creates a valid address and than it checks if the address has bitcoin.
