While it's true that actively preventing a champion from snowballing, that is a strategy that can be applied to any champion, regardless of how much or how little counterplay they actually present. It's also a much more long-term form of counterplay, when the issue of permaslows lies in a lack of moment-to-moment counterplay. One of LoL's core values is that you should always have an option to react to your opponent's plays, regardless of how fed you or they are, which translates to being able to outplay an opponent while you're fighting them, and not just over a long term meta-strategy. This is obviously not perfectly enforced, since there are quite a few champions who are low on moment-to-moment counterplay, but it's something Riot's been working on, which is why they've been keeping snowballing mechanics under tight control.

As a side note, I feel Tristana has gameplay issues fairly close to Lee Sin and pre-range nerf Lucian's: right now, she has no real weakness. She has a good early game and an amazing late game, but also has so many ways to avoid being attacked that it's overly difficult to reach her, let alone stop her. Her weakness used to be her terrible late game, which is now pretty decent due to the changes to AD itemization a few weeks back. It's difficult to fight her in lane (she has safe and highly damaging poke that also severely limits your own trading power, plus a massive gapcloser in case things go sour), difficult to build against her (even with no AP, she deals a fair amount of mixed damage) and difficult to fight her even if you have enough gapclosers to cover her range, rocket jump and massive peel. While she may need a rework, I feel Riot should focus on the changes they gave her recently, and make her super-dependent on her spells to work optimally, in exchange for having access to massive bursts of power.
