Questions

Is there a KiCad symbol and footprint for the SN74LS27N?

Yes. The symbol is 74xx:74LS27 and the footprint Package_DIP:DIP-14_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 SN74LS27N?

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

Where is the SN74LS27N datasheet?

Texas Instruments publishes it: the Datasheet link on this page opens it.

Where can I order the SN74LS27N?

JLCPCB lists it as part C2879097, with 94 in stock; the sellers' links on this page open their listings.

What can replace the SN74LS27N?

Parts like it in the library: the CD4093BE by Texas Instruments, the CD4078BE by HGSEMI, the CD4093BE(XBLW) by XBLW and the CD4030BE by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
