I am currently using EndeavourOS for my laptop. Is there a backup solution that is easy to use, and can be run from the EndeavourOS install media without internet? (RSync is included, but no other backup tools are included, to my knowledge.) I don’t want to use another ISO due to space constraints on my USB.
Borg backup. You should be able to install it on your Live session, then restore to the target mount point.
And use Vorta if you want a gui for Borg backup.
Pika Backup is another user-friendly Borgbackup GUI.

Pika Backup is the most user-friendly GUI for Borg. Vorta UI is powerful but complex. Pika only shows you the absolute basics: where to keep the backups, what to include, what to exclude, list of snapshots, and schedule options.
Vorta looks very powerful. I know all that functionality is in Borg, but it’s tricky to do it right. I’ll give Vorta a try on my next install.
BorgBackup is the answer. Stopped creating stupid shell scripts with rsync and whatever and thinking I was so clever.

As long as you don’t reboot, your live sessions act like a fully installed OS. At least with any of the LiveUSB sessions I’ve ever used over the last decade.
You can install, mount a backup image, then push it on to a mountpoint for your actual install to be restored.

Technically you are able to to do with any live environment and backup data, so the answer would be “yes”.
