I have no data to answer this. It should be considered in first place that they are not used against attacking infantry (like it often happens with mortars), but against Ukrainian-held lines, which means that the probability of bodies (in case the attack is deadly) being recovered immediately or thereafter is considerably higher (which matters in terms of MIA notices).

Occasionally there are news of personnel and officers getting killed in the tactical-operational rear, but it is not so easy to know if it had been a glide bomb instead of a missile.

That said, I am not of the opinion that the share of death toll caused by KABs is that high. They are a big problem widely recognized by the Ukrainians, but they also don’t have thaumaturgic powers, are rarely used in certain sectors and cannot be used, for obvious reasons, against every strong point.
