A bridge will not be instantiated unless there is a network interface attached to it. If the bridge is only switching external traffic (no interaction with OpenWrt routing or services), the network interface should be protocol Unmanaged (proto none in the CLI).
The "Device" of your empty network interface needs to be the bridge device, not an Ethernet port. Create the bridge first so you can select it from the list. Conventionally the network is called some name and the bridge is called br-name. This isn't a hard requirement but it makes it easier to follow.
