Questions

Is there a KiCad symbol and footprint for the KA7812ERTM?

Yes. The symbol is Pinmap_Generic:Regulator_Linear_1IN_2GND_3OUT and the footprint EasyEDA_Cloud:TO-252-2_L6.6-W6.1-P4.60-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 KA7812ERTM?

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

Where is the KA7812ERTM datasheet?

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

Where can I order the KA7812ERTM?

JLCPCB lists it as part C3748338, with 0 in stock; the sellers' links on this page open their listings.

What can replace the KA7812ERTM?

Parts like it in the library: the MC7812BDTRKG-CN by ChipNobo, the BAJ2CC0FP-E2 by ROHM Semiconductor, the CJ7812 by Jiangsu Changjing Electronics Technology (CJ) and the MC7912BT by onsemi. Check their datasheets: a part that fits the footprint may still differ in its ratings.
