How can I add components like 74LS47, 74LS90 etc to LTSpice to simulate a circuit schematic I have done in KiCad?

Some of the links on that page are out of date.

The libraries you want are most easily found here: https://github.com/kicad-spice-library/KiCad-Spice-Library/blob/master/Models/Digital Logic/74LS.LIB, though I'm not seeing 7447 (dec/7seg decode) or 7490 (decade counter) in there
