I think they probably are without seeing a picture of them.
You can get a pack of 6 [T5 T6 T7 T8 T9 T10] precision Torx screwdrivers from Amazon for about £2.75 [sorry, I don't know where you are!] with FREE postage.
I hope this helps!

Yeah, looks like a very small investment in Chinese technology might be in order
Shucks, I have no idea what a T2 must look like. As far as I could tell (without an electron microscope) my T8 is around 2.2mm point to point. While my guestimate of the case screws is around 1.2mm. Which I'm guessing is the T7.
T2 must be miniscule!
T4 is the smallest I have ever needed, and that was to completely dismantle a hard drive (just for the fun of it). But it has been several years since I did that; and I'm sure the Ifixit folks do a lot more hardware dismantling than I do.
