Questions

Is there a KiCad symbol and footprint for the LM293AD?

Yes. The symbol is EasyEDA_Pro:LM293ADR and the footprint Package_SO:SOIC-8_3.9x4.9mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the LM293AD?

SOIC-8, with 8 pins. Its footprint is drawn on this page.

Where is the LM293AD datasheet?

Texas Instruments publishes it: the Datasheet link on this page opens it.

Where can I order the LM293AD?

JLCPCB lists it as part C43498, with 50,590 in stock; the sellers' links on this page open their listings.

What can replace the LM293AD?

Parts like it in the library: the LM393D by onsemi, the LM393BID by Texas Instruments, the LM393DT by STMicroelectronics and the LM2903BID by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
