Questions

Is there a KiCad symbol and footprint for the TL497ACD?

Yes. The symbol is Regulator_Switching:TL497 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 TL497ACD?

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

Where is the TL497ACD datasheet?

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

Where can I order the TL497ACD?

JLCPCB lists it as part C2071303, with 1 in stock; the sellers' links on this page open their listings.

What can replace the TL497ACD?

Parts like it in the library: the TX4152 by XDS, the TLE63893GV50XUMA2 by Infineon Technologies, the LTC1148CS-5#PBF by Analog Devices and the LTC1148CS-5#TRPBF by Analog Devices. Check their datasheets: a part that fits the footprint may still differ in its ratings.
