The KiCad import DRCs with many clearance and silk notes against KiCad's default rules. That's expected; it is not a design to fabricate from.

Questions
What parts does the Driver use?
39 parts, built around the SN74AHCT1G125DCKR(LX), PT4115, WS2811 and 74HC04D,653-JSM. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Driver KiCad files?
From the somebox/rgb-spotlight repository on GitHub, at the commit this page was made from: the board is boards/driver/driver.kicad_pcb and its schematic boards/driver/driver.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Driver design in my own project?
Its repository states no licence, so its author keeps all rights: ask somebox before reusing the design.
