Placing a type 31 core with three turn of the AC line feeding the LED power

You don't have nearly enough turns. Study k9yc.com/RFI-Ham.pdf
But -- a FAR better solution is to replace the power supply, which is
almost certainly a switching p/s, with a linear supply have the same
voltage and current ratings.
