LotRO doesn't normally allow you to keep track of an enemy that is not targeted by yourself or a raid target assist. I say "normally" because there is one little trick that can sometimes help but it takes some getting used to. LotRO allows you to create a "detached tooltip" which is a persistant tooltip that you can use to keep track of enemies. To create a detached tooltip, hover your mouse over an enemy (or any NPC or object) and press "H". For enemies, the name, brief description and health bar will be displayed in a tooltip. You can display many tooltips simultaneously and move them around as long as you don't hit escape or close them. Clicking on a detached tooltip will switch target to that enemy.
They take a bit of getting used to, especially since hitting "escape" will close them all. When the enemy dies you will have to manually close the tooltip or it will sit there with a grey healthbar. One downside is that the tooltips will stop working if the enemy goes out of range. Once you do get used to them, you can fairly easily keep track of multiple enemies.
