Overview
The BSS127 is a MOSFET made by TDD in a SOT-23 package with 3 pins. SOT-23 MOSFETs ROHS.
PCBKit's library has its KiCad symbol (Transistors:N-MOSFET-D 1G 2S 3D, from CERN's library) and its footprint (Package_TO_SOT_SMD:SOT-23, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C55488518).

Questions
Is there a KiCad symbol and footprint for the BSS127?
Yes. The symbol is Transistors:N-MOSFET-D 1G 2S 3D and the footprint Package_TO_SOT_SMD:SOT-23, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the BSS127?
SOT-23, with 3 pins. Its footprint is drawn on this page.
Where can I order the BSS127?
JLCPCB lists it as part C55488518, with 0 in stock; the sellers' links on this page open their listings.
What can replace the BSS127?
Parts like it in the library: the 2N7002 by Diodes Incorporated, the BSS84K by hongjiacheng, the 2N7002KT by hongjiacheng and the 2N7002KM by DongChen. Check their datasheets: a part that fits the footprint may still differ in its ratings.
