Is there a KiCad symbol and footprint for the INA115BU?
Yes. The symbol is Operational Amplifiers:INA115 and the footprint Package_SO:SOIC-16W_7.5x10.3mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the INA115BU?
SOIC-16-300mil, with 16 pins. Its footprint is drawn on this page.
Where is the INA115BU datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the INA115BU?
JLCPCB lists it as part C1346324, with 0 in stock; the sellers' links on this page open their listings.
What can replace the INA115BU?
Parts like it in the library: the INA217AIDWR by Texas Instruments, the INA114AU/1K by Texas Instruments, the INA2128U by Texas Instruments and the INA2141UA/1K by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
