Early game Q harrass before she hits level 2 can be a godsend. Being an AP Carry rather than an assassin Karthus can hold a lot when it comes to DPS trades.

After level 2 you needs to keep away from her Q range. Force her to burn her W in order to get close because it's much easier to dodge her E than her W.

Try and make sure you push her in to hit your levelups before her, play like you would an ADC. You can usually tell if you're getting ganked by LeBlanc's movements. She should normally be standing behind the minionwave, if she looks like she's trying to stand closer then she's ether looking to WQE you for harrass or you're getting ganked. Ether way just back off. Land more Lay Wastes at every opportunity.
