Questions
What parts does the XHP70 LED driver use?
23 parts, built around the TPS61088RHL. 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 XHP70 LED driver KiCad files?
From the powermax555/XHP70_driver repository on GitHub, at the commit this page was made from: the board is XHP70_LED_driver.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the XHP70 LED driver design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
