Is there a KiCad symbol and footprint for the TM1622?

Yes. The symbol is EasyEDA_Cloud:HT1622B-LQ44 and the footprint Package_QFP:LQFP-44_10x10mm_P0.8mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the TM1622?

LQFP-44(10x10), with 44 pins. Its footprint is drawn on this page.

Where is the TM1622 datasheet?

TM publishes it: the Datasheet link on this page opens it.

Where can I order the TM1622?

JLCPCB lists it as part C92286, with 0 in stock; the sellers' links on this page open their listings.

What can replace the TM1622?

Parts like it in the library: the HG1622B-LQ44 by HGSEMI, the HT16L21 by Holtek Semicon, the GN1622A by GN Semic and the HT1622B-LQ44 by HGSEMI. Check their datasheets: a part that fits the footprint may still differ in its ratings.
