Questions

Is there a KiCad symbol and footprint for the LM7121IMX?

Yes. 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 LM7121IMX?

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

Where is the LM7121IMX datasheet?

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

Where can I order the LM7121IMX?

JLCPCB lists it as part C2058513, with 108 in stock; the sellers' links on this page open their listings.

What can replace the LM7121IMX?

Parts like it in the library: the TS922IDT by STMicroelectronics, the LMV358B-SR by 3PEAK, the MC33178D by onsemi and the BUF634AID by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
