Is there a KiCad symbol and footprint for the HCT6674?

Yes. The symbol is EasyEDA_Cloud:HCT6674 and the footprint Package_QFP:LQFP-64_10x10mm_P0.5mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the HCT6674?

LQFP-64(10x10), with 64 pins. Its footprint is drawn on this page.

Where can I order the HCT6674?

JLCPCB lists it as part C46469633, with 99 in stock; the sellers' links on this page open their listings.

What can replace the HCT6674?

Parts like it in the library: the HCT6678 by HCTmicro, the XTM32016384QT00351001 by TOGNJING, the SWXJHBCVE0-16.384000 by Starwave and the SWXD8ABVE0-16.384000 by Starwave. Check their datasheets: a part that fits the footprint may still differ in its ratings.
