How do we use Google Japanese Input 12-key keyboard to input Katakana as the keys are in Hiragana? For example, how do I input アinstead of あ？
Google Japanese Input only has 2 modes: kana/romaji.
There is no hiragana-only/katakana-only compared to other IMEs. However, in kana mode, the suggestion box provides hiragana (normal/small), katakana (normal/small and full/half), kanji, and recently used words as possible conversion.
Note: sometimes you need to scroll to the bottom for katakana conversion.
