Try picking up some 100'x20' sheets of black plastic sheet, from
Lowes, figure a way to moor the sheets over the areas where you want
to clear the waterlilies, I don't know how long it will take but
complete darkness should kill large areas fairly reliable. that would
be a lot of organic matter, going off...

If you can drain the pond, it's fairly easy to knife them out realy

Any small and productive Lily pad/root eating machines out there?
Any new technologies available?
