The block producer chooses transaction ordering. They control who gets sandwiched. Running your own node won't change anything.

  The trading site's performance is quite high latency, and uses a 3rd party endpoint (I forget which one) that doesn't emphasize performance. You reduce the latency of your orders, acquire real-time price information, notification of liquidity changes faster, etc. If you think it's to prevent attacks in some absolute sense, that isn't the goal. Your goal is to make life more difficult for them and/or decrease profit incentives. You only need to remove some of the profit to make it not worth someone's time to maintain, and at least you're bleeding less money if they do continue. You get to be more strategic in how you place orders and make it really annoying for a botter or force the botter to blacklist your trades from your attacks (something that has happened before). You can also identify flaws in the bot and exploit them to make it bleed money(this has been demonstrated as possible many times).
