Questions

Is there a KiCad symbol and footprint for the BU922?

Yes. The symbol is Pinmap_Generic:Q_NPN_1B_2C_3E and the footprint Package_TO_SOT_THT:TO-3, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the BU922?

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

Where can I order the BU922?

JLCPCB lists it as part C2907824, with 0 in stock; the sellers' links on this page open their listings.

What can replace the BU922?

Parts like it in the library: the 2N3055 by JSMSEMI, the 2N3055A by SPTECH, the MJ2955 by SPTECH and the MJ15022 by SPTECH. Check their datasheets: a part that fits the footprint may still differ in its ratings.
