Sure, there are already plenty of ways to do a Google search on Android. Gboard offers yet another, but it’s one you may actually want to have with you. In the settings you can turn on the “G” button and predictive search so they’re always just one touch away when you’re typing.
It may feel like overkill, but it allows you access to sports information, movie times, or other information without leaving the app. If you find yourself not using it, you can always disable the button. It’s then replaced by an arrow that expands to let you use Google Translate, change the theme, switch to one-handed typing mode, voice dictation, or access the settings.
