Is there a KiCad symbol and footprint for the SN74ALS112AD?

Yes. The symbol is 74xx:74LS112 and the footprint Package_SO:SOIC-16_3.9x9.9mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the SN74ALS112AD?

SOIC-16, with 16 pins. Its footprint is drawn on this page.

Where is the SN74ALS112AD datasheet?

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

Where can I order the SN74ALS112AD?

JLCPCB lists it as part C1550099, with 0 in stock; the sellers' links on this page open their listings.

What can replace the SN74ALS112AD?

Parts like it in the library: the 74HC76S by GR, the DM74LS174M by onsemi, the SN74LS112ADRE4 by Texas Instruments and the 74HC273D by Nexperia. Check their datasheets: a part that fits the footprint may still differ in its ratings.
