Should I use ‘gotten’ or ‘got’ in this sentence?

I think ‘got’ sounds better, but I’d rather my sentence be correct than pretty.

My sentence: The things she’d told him couldn’t be got out of her by just anyone.

Is ‘got’ correct or should I use ‘gotten’?

The things she had told him couldn't be got out of her by just anyone.

It is just a matter of usage. Both are correct.

The Americans might use gotten and the British might use got. But gotten is slowly creeping into the British Usage too.
