Generally when there is a batch of things you want to select, try using window selection rather than individual clicking.
Window selection is when you click in an empty area and drag out a selection box.
Here is a quick demo of using it with Trim:
There are 2 modes for the window select, depending on whether you drag it starting from the left going towards the right, or starting on the right going towards the left.
If you go from left to right, it will only select things that are completely contained within the window. The window outline shows as a solid line for this mode. This is often the one that you would want to use for grabbing trim fragments.
If you go from the right towards the left, it will select anything that touches the box in any way, not thing that are only fully contained. This mode will show the window with a dashed outline.
So strategic use of those can help avoid a ton of manual click selections.

It would probably be kind of tough to do that, since Trim works on a lot more than just lines as the cutting objects. There is not always one "side" available like that.
Also for a line as the cutter you should pretty much always be able to grab a window around it easily, if the cutter is angled you may want to use the 3D view so you can rotate around for a good vantage point to do the window.
If you have an example file that you are having a problem with, can you please post it so I can take a look?

Really here I would recommend using right-click instead of either of those.
Right click inside of a viewport is also an alias for hitting the "Done" button the same as enter, and it tends to be more efficient.
