Questions

Is there a KiCad symbol and footprint for the AD8644AR?

Yes. The symbol is EasyEDA_Cloud:OPA4137P and the footprint Package_SO:SOIC-14_3.9x8.7mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the AD8644AR?

SOIC-14, with 14 pins. Its footprint is drawn on this page.

Where is the AD8644AR datasheet?

Analog Devices publishes it: the Datasheet link on this page opens it.

Where can I order the AD8644AR?

JLCPCB lists it as part C4369931, with 0 in stock; the sellers' links on this page open their listings.

What can replace the AD8644AR?

Parts like it in the library: the LM2902DT by STMicroelectronics, the LM324DT by STMicroelectronics, the LMV324-SR by Gainsil and the MC33179D by onsemi. Check their datasheets: a part that fits the footprint may still differ in its ratings.
