Overview
The BSS138KA is a MOSFET made by ElecSuper in a SOT23-3L package with 3 pins. -55℃~+150℃ 1 N-channel 1.3pF 1.6nC@4.5V 15pF 300mA 350mW 60V 700mV SOT23-3L MOSFETs ROHS.
PCBKit's library has its KiCad symbol (Transistor_FET:BSS138, from KiCad's library) and its footprint (Package_TO_SOT_SMD:SOT-23-3, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C5224259).

Questions
Is there a KiCad symbol and footprint for the BSS138KA?
Yes. The symbol is Transistor_FET:BSS138 and the footprint Package_TO_SOT_SMD:SOT-23-3, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the BSS138KA?
SOT23-3L, with 3 pins. Its footprint is drawn on this page.
Where is the BSS138KA datasheet?
ElecSuper publishes it: the Datasheet link on this page opens it.
Where can I order the BSS138KA?
JLCPCB lists it as part C5224259, with 0 in stock; the sellers' links on this page open their listings.
What can replace the BSS138KA?
Parts like it in the library: the ST3422A by STANSON Tech., the AP5N10S by ALLPOWER, the FDN5618P by onsemi and the SI2309CDS-T1-GE3 by Vishay Intertechnology. Check their datasheets: a part that fits the footprint may still differ in its ratings.
