Overview
The ADR421ARMZ is a voltage Reference made by Analog Devices in a MSOP-8 package with 8 pins. -40℃~+125℃@(Ta) 1.75uVp-p 10mA 2.5V 3ppm/℃ 4.5V~18V 500uA Fixed Series ±0.12% MSOP-8 Voltage Reference ROHS.
PCBKit's library has its KiCad symbol (Reference_Voltage:ADR421ARMZ, from KiCad's library) and its footprint (Package_SO:MSOP-8_3x3mm_P0.65mm, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C659530). 4 open-source boards in 4 repositories on GitHub use it.

Questions
Is there a KiCad symbol and footprint for the ADR421ARMZ?
Yes. The symbol is Reference_Voltage:ADR421ARMZ and the footprint Package_SO:MSOP-8_3x3mm_P0.65mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the ADR421ARMZ?
MSOP-8, with 8 pins. Its footprint is drawn on this page.
Where is the ADR421ARMZ datasheet?
Analog Devices publishes it: the Datasheet link on this page opens it.
Where can I order the ADR421ARMZ?
JLCPCB lists it as part C659530, with 0 in stock; the sellers' links on this page open their listings.
What can replace the ADR421ARMZ?
Parts like it in the library: the REF5025ID by Texas Instruments, the REF5025AIDGK by Texas Instruments, the ADR421ARZ by Analog Devices and the ADR431BRZ by Analog Devices. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the ADR421ARMZ?
4 boards in 4 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
