Questions

Is there a KiCad symbol and footprint for the SS8550?

Yes. The symbol is Transistor_BJT:SS8550 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 SS8550?

SOT-23, with 3 pins. Its footprint is drawn on this page.

Where can I order the SS8550?

JLCPCB lists it as part C55127280, with 11,972 in stock; the sellers' links on this page open their listings.

What can replace the SS8550?

Parts like it in the library: the SS8050 by hongjiacheng, the SS8050 by MDD, the SS8550 by hongjiacheng and the SS8550 Y2 by Jiangsu Changjing Electronics Technology (CJ). Check their datasheets: a part that fits the footprint may still differ in its ratings.
