Is there a KiCad symbol and footprint for the INA129U?
Yes. The symbol is Amplifier_Instrumentation:INA129 and the footprint Package_SO:SOIC-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 INA129U?
SOIC-8, with 8 pins. Its footprint is drawn on this page.
Where is the INA129U datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the INA129U?
JLCPCB lists it as part C1346192, with 0 in stock; the sellers' links on this page open their listings.
What can replace the INA129U?
Parts like it in the library: the INA128UA/2K5 by Texas Instruments, the INA821ID by Texas Instruments, the AD623ARZ-R7 by Analog Devices and the INA826AID by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
