I believe the Tesla Models 3 and Y's LCD screens were a cost cutting measure -- one LCD replaces dozens of smaller screens, switches, buttons, and indicators, as well as the PCBs and metal chassis to support them and the molded plastic to hide the PCBs and chassis. It's probably also less engineering effort to put a set of controls on the screen than to design the corresponding physical controls.
