Who makes a single pole lighting switch with an indicator light for hidden light control

Everyone.
What do you mean by hidden control? Do you mean the light is hidden and you want to know if it is on?
Then yes, everyone makes them.

Means you can't see it from the switch and want to know if it's still on?

Yup
