Is there a KiCad symbol and footprint for the SA78A?

Yes. The symbol is Device:D_TVS and the footprint EasyEDA_Cloud:DO-204AC_BD3.1-L6.7-P10.00-D1.1-FD, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the SA78A?

DO-15(DO-204AC), with 2 pins. Its footprint is drawn on this page.

Where is the SA78A datasheet?

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

Where can I order the SA78A?

JLCPCB lists it as part C1979042, with 0 in stock; the sellers' links on this page open their listings.

What can replace the SA78A?

Parts like it in the library: the SMCJ78A by hongjiacheng, the SMAJ78A by BORN, the SMAJ78A/TR13 by Brightking and the SMAJ78CA/TR13 by Brightking. Check their datasheets: a part that fits the footprint may still differ in its ratings.
