This is really complicated. Ideally I’d make a tutorial video for you but it’s not my thing. You might get some idea of techniques from this video
Also read the guide to learn about editing titles (objects like lines are added as titles), frame and fit, key frames etc
One thing to watch is that LumaFusion always rotates frames around the centre so if you want to rotate a line around its end the end must be in the centre of the frame although the frame itself can be offset
To gradually reveal a line you need to cover it with another overlay of the original video but cropped slowly to reveal the title and original video underneath.
Sorry this is quite complicated. If FCP takes less than a minute I’d use that (if I had a computer!)
Can anyone else help?
