Questions

Is there a KiCad symbol and footprint for the MIC2155YML-TR?

Yes. The symbol is EasyEDA_Cloud:MIC2155YML-TR and the footprint EasyEDA_Cloud:TQFN-32_L5.0-W5.0-P0.50-BL-EP3.1, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the MIC2155YML-TR?

VQFN-32-EP(5x5), with 33 pins. Its footprint is drawn on this page.

Where is the MIC2155YML-TR datasheet?

Microchip Technology publishes it: the Datasheet link on this page opens it.

Where can I order the MIC2155YML-TR?

JLCPCB lists it as part C632065, with 0 in stock; the sellers' links on this page open their listings.

What can replace the MIC2155YML-TR?

Parts like it in the library: the MAX15301AA02+TCJK by Maxim Integrated (Analog Devices), the MAX1540AETJ+T by Maxim Integrated (Analog Devices), the MAX1540ETJ by Maxim Integrated (Analog Devices) and the MAX8795AETJ+ by Maxim Integrated (Analog Devices). Check their datasheets: a part that fits the footprint may still differ in its ratings.
