Questions

Is there a KiCad symbol and footprint for the HT317ARDZ?

Yes. The symbol is EasyEDA_Cloud:CX1117ASTNI and the footprint Package_TO_SOT_SMD:SOT-223, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the HT317ARDZ?

SOT-223, with 4 pins. Its footprint is drawn on this page.

Where is the HT317ARDZ datasheet?

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

Where can I order the HT317ARDZ?

JLCPCB lists it as part C2898742, with 2,164 in stock; the sellers' links on this page open their listings.

What can replace the HT317ARDZ?

Parts like it in the library: the LM317G by UMW, the LM317DCYR by UMW, the LM317 by TDSEMIC and the TL1963A-33DCY by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
