I did see some that looked to be the same with the word balun in it. I
doubt any of those would have an actual balun type of transformer in

looking at the ones that do not hae the word balun in the description.

They probably use the word balun to describe going from a ballanced 2
wire system to one that is not balanced.

These *are* transformer-based devices and not designed for any level of current other than AV signal currents.

Apart from all that, using an RCA jack or plug for the stated purpose is just not a very good solution in the first place.
