Questions

Is there a KiCad symbol and footprint for the BL78M09?

Yes. the footprint EasyEDA_Cloud:TO-252-2_L6.6-W6.1-P4.57-LS10.0-BR-CW, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the BL78M09?

TO-252, with 3 pins. Its footprint is drawn on this page.

Where is the BL78M09 datasheet?

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

Where can I order the BL78M09?

JLCPCB lists it as part C21882551, with 2,410 in stock; the sellers' links on this page open their listings.

What can replace the BL78M09?

Parts like it in the library: the L7809CVAT by GREENMICRO, the TP78M09K3-1 by TECH PUBLIC, the L7809CKT by GREENMICRO and the L7809CV(XBLW) by XBLW. Check their datasheets: a part that fits the footprint may still differ in its ratings.
