How do I create this as a string under OH3?

To create an Item

Rules with widget on off

In items, just hit the plus button, give it a nane and set type switch. Don‘t link it to a thing/channel.

official version, somewhat hidden under Semantics

Semantic Model

No idea what you want to do with this, but once its in an Item state you can do whatever with it.
