Questions

Is there a KiCad symbol and footprint for the LR7540-T?

Yes. The symbol is Pinmap_Generic:Regulator_Linear_1GND_2OUT_3IN and the footprint Package_TO_SOT_SMD:SOT-23-3, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the LR7540-T?

SOT-23-3, with 3 pins. Its footprint is drawn on this page.

Where is the LR7540-T datasheet?

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

Where can I order the LR7540-T?

JLCPCB lists it as part C486071, with 0 in stock; the sellers' links on this page open their listings.

What can replace the LR7540-T?

Parts like it in the library: the AP2210N-4.0TRG1 by Diodes Incorporated, the MD5340 by Shanghai Mingda Microelectronics, the MD7540 by Shanghai Mingda Microelectronics and the BL8503-40PRM by BL. Check their datasheets: a part that fits the footprint may still differ in its ratings.
