I'm exploring an OS for my budget laptop and discovered Lubuntu. Since I've learned little about it online, am I sure it's the real deal or just a tweaked version of Ubuntu? It seems similar to Windows Lite you might have heard of.
If it's a modified version, you should use it only if the manufacturer supports it. Even modified software can lose its original identity and may not receive proper updates or security fixes.
Every Linux distribution is altered. There’s nothing truly original beyond the base kernel. For instance, Ubuntu builds upon Debian.
I think you mean Xubuntu, as you said Ubuntu uses Gnome. Also you can simply install Ubuntu, and then install any other desktop environment you want, but obviously it is easier to go with the flavor that includes the desktop environment you want out of the box. Linux doesn't work the same as Windows, where you have an original version from the developer and some unofficial one. In a sense, Ubuntu is just a modified Debian. As long as a Linux distribution has a community, you have "support".
