Questions

Is there a KiCad symbol and footprint for the HT24LC64?

Yes. The symbol is EasyEDA_Cloud:24FC256-I_ST and the footprint Package_SO:SOP-8_3.76x4.96mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the HT24LC64?

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

Where is the HT24LC64 datasheet?

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

Where can I order the HT24LC64?

JLCPCB lists it as part C73710, with 7,287 in stock; the sellers' links on this page open their listings.

What can replace the HT24LC64?

Parts like it in the library: the AT24C64M/TR by HGSEMI, the 24AA32AT-I/SN by Microchip Technology, the P24CM01B-SSH-MIR by PUYA and the 24LC16BT-I/SN-TUDI by Tudi. Check their datasheets: a part that fits the footprint may still differ in its ratings.
