Questions

Is there a KiCad symbol and footprint for the 78M09?

Yes. The symbol is Pinmap_Generic:Regulator_Linear_1IN_2GND_3OUT and the footprint EasyEDA_Cloud:TO-252-2_L6.6-W6.1-P4.57-LS9.9-BR-CW, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the 78M09?

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

Where is the 78M09 datasheet?

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

Where can I order the 78M09?

JLCPCB lists it as part C347281, with 17,313 in stock; the sellers' links on this page open their listings.

What can replace the 78M09?

Parts like it in the library: the LM7809T by HGSEMI, the CJ7809 by Jiangsu Changjing Electronics Technology (CJ), the MC7809CT by onsemi and the L7809CV(UMW) by UMW. Check their datasheets: a part that fits the footprint may still differ in its ratings.
