I'm using Wayland and libinput on an X1 Carbon, which I'd expect to use a very comparable touchpad, and it works flawlessly. I easily can move the mouse by individual pixels by just rolling my finger, or throw it across the screen. You may want to experiment with your desktop environment's mouse settings, and if that doesn't help, you should consider providing a detailed report to the libinput folks and see if they can address it.
