But this is only the hole edge to board edge without any copper, not THT pad copper to board edge?
“It depends” and there’s no spesific setting for that in KiCad rules. Is the edge routed or made with V-score? For the latter it may make no difference for the manufacturer but the tolerance is worse. Even for the former the manufacturer may not care. It’s even one possible technique to get sharp inner corners to create a drilled hole which overlaps the edge line, so they probably will accept it. It’s up to you to know what you can tolerate.
Find out the manufacturer edge tolerance and drill tolerances and try to calcluate or guess if there’s enough board left between them for your purposes. Then ask the manufacturer if they accept it or add information that they shouldn’t care about the possible broken hole edge if they just can accept it.
