Questions

Is there a KiCad symbol and footprint for the OPA2991IPW?

Yes. The symbol is EasyEDA_Cloud:OPA2991QDGKRQ1 and the footprint Package_SO:TSSOP-8_4.4x3mm_P0.65mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the OPA2991IPW?

TSSOP-8, with 8 pins. Its footprint is drawn on this page.

Where is the OPA2991IPW datasheet?

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

Where can I order the OPA2991IPW?

JLCPCB lists it as part C4366310, with 26 in stock; the sellers' links on this page open their listings.

What can replace the OPA2991IPW?

Parts like it in the library: the RS622AXQ by Jiangsu RUNIC Tech, the WS72412H-8/TR by WILLSEMI, the AD8532ARUZ by Analog Devices and the TLV9102IPW by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
