Questions

Is there a KiCad symbol and footprint for the 78L12?

Yes. 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 78L12?

SOT-89, with 5 pins. Its footprint is drawn on this page.

Where is the 78L12 datasheet?

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

Where can I order the 78L12?

JLCPCB lists it as part C22391049, with 0 in stock; the sellers' links on this page open their listings.

What can replace the 78L12?

Parts like it in the library: the BL79L12 by Galaxy Microelectronics, the PJ78M12SQ by PJSEMI, the 78L12 by GAOGE MICROCHIP and the LM78L12PKR by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
