The expression 'overkill solution' sounds awkward in English. 'Overkill' is mostly informal and is usually a noun (not an adjective); e.g., "This is ridiculous overkill." A better translation of 'overkill' as an adjective in 'This is an overkill solution' might be "Questa è una soluzione drastica," which sounds idiomatic to a native Italian speaker.
