Can you guys recommend a way to do this?
Yes.
Use THS4131 with LT5400 for proper common-mode reject and converting symmetrical (balanced) line to unsymmetrical (unbalanced).
Use unsymmetrical (unbalanced) relay-based stepped or R2-R attenuator
Use THS4131 with output filter and common-mode choke for proper forming of output symmetrical (balanced) signal and rejecting noise from the output.
Of course. You can configure this board however you need.
Balanced Strereo Attenuator

Would this autoformer attenuator work?

That's for low power, unbalanced, low-fi background and PA systems (at speaker level).
