You misunderstand the problem. APP did not say they they don't have ILS available, it said it will take some time before a long enough gap exists between incoming traffic so they can allow for LH to insert themselves for landing.
In aviation, times are almost always estimates, not hard figures. Just like when the captain announces every 15 minutes there will be 15 minutes more delay, the same happens when controllers have other things to do, they route you over a holding pattern until they can deal with you.
And seriously, you don't delay 20-30 flights because one non emergency flight can't do visual approaches at night.
