My guess is a bacteria or fungus that invaded independently or subsequent to a mechanical or insect injured area on the liropes' leaves. Sometimes a nutrient deficiency is the cause. It could be weather related, in which case enduring it is all that can be done. I'm going by the light, discolored area ringing each spot. Personally, I would do nothing yet, just keep an eye on things to see if any further damage occurs.

Liriope are pretty tough plants, but some varieties are tougher and more resistant to problems than others.

Loses

I’m wondering what made the hole? Bees? Wasps? Hornets? Snakes? The soil looks very pellety

I'm guessing ants!
