No. Having the ability to fight against the trolls has no relationship with "weakness". The Winx is able to defeat the Trix, but they never be the Trix's weakness... In the other hand, Tritannus was Icy's weakness.

Hmm... The flying basiliks just get defeated if they use that ray on themselves. Means if they don't use the ray/they don't attack, nothing happens. The same thing with Stella's attack is above.
