Please note that the LCD module was not intended to ship with the 2017/18 model kits. So consider it a "Free bonus" part
Q: is there software to run the LCD module?
A: Sorry, no. We didn't intend on it to ship with the kits.
Q: The LCD module is not physically supported on the frame
A: That is correct. From the Landzo documentation (see picture below, we see that it just hangs over the edge of the PCB.
<ToDo: Look at what would be needed to provide a support bracket that could be 3D printable using an FDM printer and post to thingiverse.>
