You did a pretty good job protecting yourself from getting edge guarded while on the ledge, and generally made good use of TL's grabs. Your follow-ups to hitting the opponent with projectiles were good, and did a very good job making it the nightmare it should be for the opponent to get back to the ground from being above the stage. Uthrow > uair/throw at bomb in the air is good.
Bomb pulls should usually be done from the air, since they're easy to punish when they're used on the ground. You should jump more when using the bombs and boomerang, too. Also, you shouldn't roll. Rolls in general are easy to punish most of the time, and you did get your rolls punished quite a few times in that match, plus TL's rolls are extremely bad compared to most of the other characters. Camping too much against Falco is also a bad idea, since not only does he have a reflector for throwing your projectiles right back at you, but he still has a very good projectile of his own. You should pummel when you grab people, which is especially important as TL since he has one of the better pummels in the game. Also, while I didn't see much of a problem with you getting gimped in the video, mixing up your recovery with the tether + spin attack is always a good idea to make yourself harder to gimp. There were also a few times where the opponent know you were going to run and throw a bomb at them, so they sat there in their shield, which you could've punished by running up to them, grabbing, and immediately dthrowing or fthrowing (immediately because you have some invincibility during those throws, so wait too long will get you hit by the bomb).
I think your zair usage at the end would've been a lot more helpful for you if you knew the timing for inputting the zair. I suggest practicing landing zair on Greninja in training mode. Once you have that down you should move on to JCBT (jump canceled bomb throws; also I apologize if you know this already, but I didn't see you use them in the video). Basically, you can do JCBT by, when running with a bomb, pressing X then immediately pressing A to throw the bomb (it helps to quickly "roll" your thumb from X to A). If you did it right you should do a grounded bomb throw and have significantly reduced ending lag on that bomb throw, which you can test by immediately dashing into the bomb.
So yeah, hope this helps.
