Is there a KiCad symbol and footprint for the 74LS240PC?
Yes. The symbol is 74xx:74LS240 and the footprint Package_DIP:DIP-20_W8.89mm_SMDSocket_LongPads, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the 74LS240PC?
PDIP-20, with 20 pins. Its footprint is drawn on this page.
Where is the 74LS240PC datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the 74LS240PC?
JLCPCB lists it as part C3755973, with 0 in stock; the sellers' links on this page open their listings.
What can replace the 74LS240PC?
Parts like it in the library: the SN74HC244N(LX) by lingxingic, the AIP74HC540DA20.TB by Wuxi I-core Elec, the AIP74HC541DA20.TB by Wuxi I-core Elec and the 74HC244N-HX by ZHHXDZ. Check their datasheets: a part that fits the footprint may still differ in its ratings.
