When I read that paragraph as a layman, I read two points:
1. A US entity does not have to redesign anything to slow or prevent infringing search results/credit card payments/etc in order to avoid liability
2. No particular type of technology must be utilized to comply: they're explicitly saying they won't require firms to "use PiracyBlocker2001 on your network" or "filter search results with the ProtectLouisVuittonsProfitMargin algorithm" or something to that effect.
