The BOM and SMT placement file (CPL) are formatted for use with JLCPCB.
Apart from the keys, encoders, the USB-connector and the LED matrix driver all parts can be populated by JLCPCB. The schematic contains the LCSC partnumbers in the attributes of each part.
Keys
All keys compatible with Cherry MX 2 or 3 pin should fit the board.
Encoders
The encoders a standard rotary encoders, just search ebay/aliexpress/amazon or your local electronics dealer.
