Type Tool is in with the Pen Tool Group CC 2019
The Type Tool is in the Pen Tool Group! Has to be a glitch!
Marking it as resolved, since the tools can be grouped in toolbar as per your wish.

Sorry to arrive only now, but there's been a new option in Ai to customize the toolbar. Thing is, sometimes, you might drag a tool inside another group (that can be undone by reseting the tool panel. And that has been corrected with the latest release in beta.
