Questions
What parts does the LTS LED Roulette 24-LEDs use?
61 parts, built around the B3F-1000. 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 LTS LED Roulette 24-LEDs KiCad files?
From the DaddySun/LTS_LED-Roulette_24-LEDs repository on GitHub, at the commit this page was made from: the board is LTS_LED-Roulette_24-LEDs.kicad_pcb and its schematic LTS_LED-Roulette_24-LEDs.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the LTS LED Roulette 24-LEDs design in my own project?
Its repository states no licence, so its author keeps all rights: ask DaddySun before reusing the design.
