The answer is a clear yes.

In short: Choose your tool that will suit you throughout your degree and really dig into it and learn it now while doing your paper.

Long version:

This is absolutely common and I’m not aware of a text editor which supports footnotes but doesn’t support automatically numbering and referencing.

In latex there’s actually a \footnote that takes care of that. In libre office, if I recall correctly, it’s Insert -> Footnote and I’m sure there are templates with the proper formatting and font sizing already in place.

Now it sounds like you’re quite early in your higher degree career - depending on your goals and future challenges you might want to either go the easiest route or really dig into writing-based formatting: It’s just faster if you’re typing all the time to not switch to a mouse to inert footnotes - but only if your really used to it.
