Questions

Is there a KiCad symbol and footprint for the LM3485MM?

Yes. The symbol is EasyEDA_Cloud:LM3485Q1MM_NOPB and the footprint Package_SO:MSOP-8_3x3mm_P0.65mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the LM3485MM?

MSOP-8, with 8 pins. Its footprint is drawn on this page.

Where is the LM3485MM datasheet?

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

Where can I order the LM3485MM?

JLCPCB lists it as part C18720, with 652 in stock; the sellers' links on this page open their listings.

What can replace the LM3485MM?

Parts like it in the library: the PAM2401SCADJ by Diodes Incorporated, the MCP16311-E/MS by Microchip Technology, the TPS62160DGKR by Texas Instruments and the ADP1613ARMZ-R7 by Analog Devices. Check their datasheets: a part that fits the footprint may still differ in its ratings.
