Is there a KiCad symbol and footprint for the OPA631U?
Yes. The symbol is EasyEDA_Cloud:OPA631U and the footprint Package_SO:SO-8_3.9x4.9mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the OPA631U?
SOIC-8, with 8 pins. Its footprint is drawn on this page.
Where is the OPA631U datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the OPA631U?
JLCPCB lists it as part C5702655, with 0 in stock; the sellers' links on this page open their listings.
What can replace the OPA631U?
Parts like it in the library: the LMV552M/TR by HGSEMI, the TLV379M/TR by HGSEMI, the OPA338UA(UMW) by UMW and the TLV2632IDR(UMW) by UMW. Check their datasheets: a part that fits the footprint may still differ in its ratings.
