Questions

Is there a KiCad symbol and footprint for the 74AC74M?

Yes. The symbol is Standard Logic:7474 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 74AC74M?

SOIC14, with 14 pins. Its footprint is drawn on this page.

What can replace the 74AC74M?

Parts like it in the library: the MC1496D by onsemi, the CD4069 by Gcore, the LM2907D-14RG by HANSCHIP semiconductor and the TCAN1046AVDRQ1 by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the 74AC74M?

14 boards in 10 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
