ChatBubbles VS FFXIVQuickLauncher

No, but you can easily edit it to get it back: https://github.com/Haplo064/ChatBubbles/issues/52

The FFXIVLauncher Mod API does implement Chatbubbles if this is a feature that would improve your quality of life.

If he was on trial, he needs to delete the trial installation, and reinstall the game. I had similar issues on Steam. The https://goatcorp.github.io/ is also a great, 3rd party solution and might even be faster than the game launcher.

All i have to say is GL... Firstly, Librem runs on a linux kernel, which is not innately compatiable with FFXIV. There are ways around this, the main way is using the xivquicklauncher 3rd party tool. https://github.com/goatcorp/FFXIVQuickLauncher

The game really is that big, though the launcher does throttle download speeds. If this is less than your usual download speed, then I would consider looking into XIVQuickLauncher, which should be significantly faster. However, if this is a pretty typical download speed, all this would accomplish is restarting your download.

I recommend using the ffxiv quicklauncher instead of official one. I used to have problems with download speeds too but with this it works as good as it should. Not to mention all the other great features it offers https://github.com/goatcorp/FFXIVQuickLauncher

Easiest fix would probably be reinstall. I've used https://github.com/goatcorp/FFXIVQuickLauncher to install in the past as the download speed is much much faster (and ffxiv is huge). You can just use the normal Square launcher afterward if you want, too, but if you're sketch about putting your username/password in a 3rd party app that's understandable.
