Is there a KiCad symbol and footprint for the SN74LVC240ANS?

Yes. The symbol is 74xx:74HC240 and the footprint EasyEDA_Cloud:SO-20_L12.6-W5.3-P1.27-LS7.8-BL, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the SN74LVC240ANS?

SO-20-208mil, with 20 pins. Its footprint is drawn on this page.

Where can I order the SN74LVC240ANS?

JLCPCB lists it as part C1548212, with 0 in stock; the sellers' links on this page open their listings.

What can replace the SN74LVC240ANS?

Parts like it in the library: the SN74ACT245NSR by Texas Instruments, the SN74F244NS by Texas Instruments, the SN74HCT541NSR by Texas Instruments and the SN74LVT244BNSR by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the SN74LVC240ANS?

2 boards in 2 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
