Questions

Is there a KiCad symbol and footprint for the BL78L09?

Yes. The symbol is EasyEDA_Cloud:78L05_C842819 and the footprint Package_TO_SOT_SMD:SOT-89-3, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the BL78L09?

SOT-89, with 3 pins. Its footprint is drawn on this page.

Where is the BL78L09 datasheet?

Galaxy Microelectronics publishes it: the Datasheet link on this page opens it.

Where can I order the BL78L09?

JLCPCB lists it as part C21882532, with 0 in stock; the sellers' links on this page open their listings.

What can replace the BL78L09?

Parts like it in the library: the HR79L09V by hongjiacheng, the FS79L09 by FOSAN, the HR78L09VS by hongjiacheng and the 78L09 by GAOGE MICROCHIP. Check their datasheets: a part that fits the footprint may still differ in its ratings.
