Once it locks you it has a constant amount of Time after which it dashes at you regardless of its rotation, what you can do is it hit it while it is not charging or Time your dashes before he actually dashes, in general when it is charging it is better to play it more defensively
not really, after it bounces off walls (TK1 it goes into reset for 1 seconds) the same goes for TK2 (it stays in the middle for 1.5 s) in that window you can hit it without any drawbacks
