I haven't done full teardown yet on this device, the led driver casing seems to be glued outside of the tube, not exactly assembled inside the tube like this T8 wifi here Using cloudcutter, I was able to verify that's it using T chip.
On the stock firmware, it was added as light strip device in the tuya app.
