Questions
Is there a KiCad symbol and footprint for the LR7544-M?
Yes. The symbol is Pinmap_Generic:Regulator_Linear_1GND_2IN_3OUT and the footprint Package_TO_SOT_SMD:SOT-89-3, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the LR7544-M?
SOT-89-3, with 3 pins. Its footprint is drawn on this page.
Where is the LR7544-M datasheet?
LR publishes it: the Datasheet link on this page opens it.
Where can I order the LR7544-M?
JLCPCB lists it as part C486079, with 40 in stock; the sellers' links on this page open their listings.
What can replace the LR7544-M?
Parts like it in the library: the HT7544-1 by UMW, the HT7144-1 by MSKSEMI, the H7544-1 by Shanghai Siproin Microelectronics and the HT7544-1 by TDSEMIC. Check their datasheets: a part that fits the footprint may still differ in its ratings.
