[noun] + が + きらい きらいな + [noun]
きらい (きらい嫌い in kanji) means "dislike". It is a な-adjective, not a verb: the thing you dislike takes が, the person who dislikes it takes は, and the sentence ends in です or だ.
English makes the disliked thing an object, which pulls learners towards を.
Before a noun, きらい takes な.
きらい states the dislike flatly, and said about someone's cooking or someone's friend in front of them, it is blunt. すき好きじゃない, "don't like", says the same thing more softly, and it is the usual choice when the person who made or chose the thing is listening.
These go beyond a plain statement of dislike.
The negative, きらいじゃない or きらいではない, means "I don't dislike it". It is a guarded way to say you quite like something without going as far as すき好き.
