Time stop just means you can act without the "timeline moving forward," or time passing. It doesn't affect the timeline, or anything changing the timeline, at all, it just pauses it temporarily. Quite simply, when time stop is "active" KC can't erase time, because, well, it can't do anything, and SP/TW wins. But if KC is activated, and SP/TW stop time within time skipping, all their actions within time stop are just that - actions - but occuring instantaniously. Epitaph would see them teleporting to a different position, and then they'd end up wherever they would have, just like everyone else when KC is used.

Time stop is called the strongest ability because no one can do anything during it, and the user can do whatever he wills. However, the stand SP/TW cannot use time stop infinitely, and have weaknesses. While it's a genuinely unbeatable ability, the stands and users still have genuine weaknesses that aren't invalidated. Jotaro wasn't even able to beat Ratt, a stand that isn't particularly powerful, because it played to its strengths and to SP's weaknesses, mainly range. DIO himself also mentions that if Polnareff was a little faster and accurate, he would've beaten him with SC, through the use of a suprise attack. So don't act like the stand and its user aren't beatable, just the ability in its rawest form is.
