Is there a KiCad symbol and footprint for the HT16K33?

Yes. The symbol is EasyEDA_Cloud:HT16K33A-28SSOP and the footprint Package_SO:SOIC-28W_7.5x17.9mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the HT16K33?

SOP-28-300mil, with 28 pins. Its footprint is drawn on this page.

Where is the HT16K33 datasheet?

Holtek Semicon publishes it: the Datasheet link on this page opens it.

Where can I order the HT16K33?

JLCPCB lists it as part C87502, with 0 in stock; the sellers' links on this page open their listings.

What can replace the HT16K33?

Parts like it in the library: the CS5817A by CHIPSEA and the HT16C21 by Holtek Semicon. Check their datasheets: a part that fits the footprint may still differ in its ratings.
