Questions

Is there a KiCad symbol and footprint for the 74HCT20D?

Yes. The symbol is EasyEDA_Cloud:SN74F21DRE4 and the footprint Package_SO:SOIC-14_3.9x8.7mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the 74HCT20D?

SO-14, with 14 pins. Its footprint is drawn on this page.

Where can I order the 74HCT20D?

JLCPCB lists it as part C5542941, with 0 in stock; the sellers' links on this page open their listings.

What can replace the 74HCT20D?

Parts like it in the library: the CD4093BM96 by Texas Instruments, the CD4078BM96 by Texas Instruments, the SN74LS21D by Texas Instruments and the CD4030BM96 by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
