After a month or so of waiting and prodding around, I've managed to dump the stock firmware off the Rockchip revision LeapPad Academy, version EPIC4.user.1.7.2109.312280833:

The firmware can be flashed using RKDevTool 2.69 and later. I did test the system (super), boot and recovery partitions and they do seem to work fine, but don't blame me if anything happens to your device.
I have also included two uboot images in the package: the stock factory uboot based on the latest available OTA update, and a hacked one with the anti-dump code patched out. Make sure to flash back to stock uboot in case LeapFrog issues a new OTA update! Mad props to pseudolobster and RedScorpioXDA for the uboot hack discovery and imgRePackerRK, respectively, without which would make this effort impossible.
