Gavin, you should look more carefully at the other shapes on the same folio in the same handwriting.
Not all of the "i" letters are not dotted and it was extremely common for dots to be left out, sometimes part of the time, sometimes frequently, depending on the scribe.
I really do not believe this is a "u" in front of "l". It is written like the other "i" letters and not like the other "u" letters. You are overlooking other words (common ones) that this might be. "Multos" is not the only word that ends in -ltos. Did you even check the other words?
