Is there any way to find a similar schematic of an RF temp sensor with an LCD display without any microcontroller involved?

Did you check without the display, The mp probably is under

Right. Black epoxy blob of chip-on-board seems to be visible in the photo, below LCD.

Yessss... as far as I can see from the photos now, there is a black epoxy blob of chip-on-board under the display.
I suppose it would be much more complex to avoid a microcontroller for such kind of projects.
