Those glide bombs have a range of about 40 miles. If a target has good air defence with a range of more than 40 miles, it's safe, and if it doesn't, it's not. Air defences with that sort of range include, first and foremost, fighters, and also long-range SAMs like Patriot, SAMP/T, and S-300. Ukraine used to have stuff like that, and so wasn't getting glide-bombed, but now doesn't, so it is. If their air defence was even weaker, yes, the Russians could just gravity bomb them. But they haven't reached that point yet.
