In a light novel, manga or such, 「……っ！」 without any preceding kana describes
the speaker is speechless or breathless for a moment. Usually it expresses a
strong surprise, anger, confusion or any "breathtaking" feelings.

"Tch" to express one's irritation is usually [ちっ or
ちぇっ](https://jisho.org/word/%E3%83%81%E3%82%A7).
