Overview
The S8550 is a bipolar Transistors BJT made by powersilicon in a SOT-23 package with 3 pins. 1 PNP 100nA 150MHz 25V 300mW 350 500mA 5V 600mV PNP SOT-23 Bipolar (BJT) ROHS.
PCBKit's library has its KiCad symbol (Transistor_BJT:S8550, from KiCad's library) and its footprint (Package_TO_SOT_SMD:SOT-23, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C2840973).

Is there a KiCad symbol and footprint for the S8550?
Yes. The symbol is Transistor_BJT:S8550 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 S8550?
SOT-23, with 3 pins. Its footprint is drawn on this page.
Where is the S8550 datasheet?
powersilicon publishes it: the Datasheet link on this page opens it.
Where can I order the S8550?
JLCPCB lists it as part C2840973, with 0 in stock; the sellers' links on this page open their listings.
What can replace the S8550?
Parts like it in the library: the PBSS4140T by Nexperia, the S9012 by Guangdong Hottech, the S8550-2TY by ShunYe and the BC817-40-TP by Micro Commercial Components. Check their datasheets: a part that fits the footprint may still differ in its ratings.
