Questions

Is there a KiCad symbol and footprint for the BC817?

Yes. The symbol is Transistor_BJT:BC817 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 BC817?

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

Where is the BC817 datasheet?

Nexperia publishes it: the Datasheet link on this page opens it.

Where can I order the BC817?

JLCPCB lists it as part C8658, with 25,671 in stock; the sellers' links on this page open their listings.

What can replace the BC817?

Parts like it in the library: the S8050 by YONGYUTAI, the MMBTA92 by hongjiacheng, the MMBTA42 by hongjiacheng and the MMBT2907ALT1G by onsemi. Check their datasheets: a part that fits the footprint may still differ in its ratings.
