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 V1-easyeda use?
43 parts, built around the SN74AHCT1G125DCKR(LX), WS2811, 74HC04D,653-JSM and 78L05G-AB3-R. 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 V1-easyeda KiCad files?
From the somebox/rgb-spotlight repository on GitHub, at the commit this page was made from: the board is archive/v1-easyeda/v1-easyeda.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 V1-easyeda design in my own project?
Its repository states no licence, so its author keeps all rights: ask somebox before reusing the design.
