Is there a KiCad symbol and footprint for the ISO7331FCDW?

Yes. The symbol is Isolator:ISO7331FC and the footprint Package_SO:SOIC-16_3.9x9.9mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the ISO7331FCDW?

SOIC-16, with 16 pins. Its footprint is drawn on this page.

Where is the ISO7331FCDW datasheet?

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

Where can I order the ISO7331FCDW?

JLCPCB lists it as part C2871433, with 0 in stock; the sellers' links on this page open their listings.

What can replace the ISO7331FCDW?

Parts like it in the library: the Π141M31 by 2Pai Semi, the CA-IS3731LN by Chipanalog, the Π131M31 by 2Pai Semi and the Π141U31 by 2Pai Semi. Check their datasheets: a part that fits the footprint may still differ in its ratings.
