Is there a KiCad symbol and footprint for the SN74HC42D?

Yes. The symbol is 74xx:74LS42 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 SN74HC42D?

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

Where is the SN74HC42D datasheet?

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

Where can I order the SN74HC42D?

JLCPCB lists it as part C469858, with 2,324 in stock; the sellers' links on this page open their listings.

What can replace the SN74HC42D?

Parts like it in the library: the 74HC4053M/TR by HGSEMI, the SN74HC138D by Texas Instruments, the 74HC138D by JSMSEMI and the MC74HC138AD by onsemi. Check their datasheets: a part that fits the footprint may still differ in its ratings.
