Is there a KiCad symbol and footprint for the OPA637SM?
Yes. The symbol is EasyEDA_Cloud:OPA637BM and the footprint Package_TO_SOT_THT:TO-99-8, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the OPA637SM?
TO-99-8, with 8 pins. Its footprint is drawn on this page.
Where is the OPA637SM datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the OPA637SM?
JLCPCB lists it as part C4366182, with 0 in stock; the sellers' links on this page open their listings.
What can replace the OPA637SM?
Parts like it in the library: the AD549JHZ by Analog Devices, the LM1558H by Texas Instruments, the LM158AH/883 by Texas Instruments and the LM101AH/883 by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
