Something like the following should do the trick:
[mcu lis_hotend]
# Change <mySerial> to whatever you found above. For example,
# usb-Klipper_rp2040_E661640843545B2E-if00
serial: /dev/serial/by-id/usb-Klipper_rp2040_<mySerial>-if00
[mcu lis_bed]
# Change <mySerial> to whatever you found above. For example,
# usb-Klipper_rp2040_E661640843545B2E-if00
serial: /dev/serial/by-id/usb-Klipper_rp2040_<mySerial>-if00
