Questions

Is there a KiCad symbol and footprint for the 74LCX74M?

Yes. The symbol is 74xx:74HC74 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 74LCX74M?

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

Where is the 74LCX74M datasheet?

STMicroelectronics publishes it: the Datasheet link on this page opens it.

Where can I order the 74LCX74M?

JLCPCB lists it as part C19434467, with 0 in stock; the sellers' links on this page open their listings.

What can replace the 74LCX74M?

Parts like it in the library: the SN74LVC74AD by Texas Instruments, the 74LVC74AD/AU118 by Nexperia, the 74LVC74AD/C118 by Nexperia and the 74LVC74AD/S400118 by Nexperia. Check their datasheets: a part that fits the footprint may still differ in its ratings.
