As you have hundreds, I only have about a dozen and I do not know how many Frilly has I so see why you do not want to dig but at the same time, if it is into the roots of you daylilies, you will never win but keep spending a lot of money, forever.
I want to get rid of it permanently, it can be done and saves a lot of misery.
That is why I wrote dig down to the main root, not some rhizome and treat that, that kills. I did it, also with Canadian Thistle which is nearly as miserable to get rid of.
At that:
How often do you have to treat your flowers?
If you are continually spraying all you are doing is killing the grass that sprouts and will continue to do so without end.
It will save you money if you use Fusilade DX rather than Fusilade II, here are the SDS sheets that show components are the same:
