There are two ways of creating hanging indent on Google Docs.
If you only need to indent one item, the more straightforward way is to use the ruler. Select the text and simply drag the triangle and the rectangle to the desired hanging indent, and then move the rectangle back to zero.
If you have a list of items you want to apply a hanging indent to, there is an easier way instead of manually doing this to every line.
Select the desired text. Click Format, select Align and indent and Indentation options.
Then, in Special indent select Hanging and select the indentation space you want to use.
