Questions

Is there a KiCad symbol and footprint for the LMT85LP?

Yes. The symbol is EasyEDA_Cloud:TMP236AQDBZTQ1 and the footprint Package_TO_SOT_THT:TO-92L, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the LMT85LP?

TO-92, with 3 pins. Its footprint is drawn on this page.

Where is the LMT85LP datasheet?

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

Where can I order the LMT85LP?

JLCPCB lists it as part C75856, with 530 in stock; the sellers' links on this page open their listings.

What can replace the LMT85LP?

Parts like it in the library: the DS18B20+ by Maxim Integrated (Analog Devices), the LM35DZ/NOPB by Texas Instruments, the MY18B20LD10 by Mysentech and the MY18E20 by Mysentech. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the LMT85LP?

3 boards in 2 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
