The LP is a big jump, yes. And not to be the party pooper, but 150mm is a little high IMO for a teenager (not to offend, I promise... just my honest opinion).
If you must go higher than 120mm, I think the Bibi is a great option. Otherwise, what about adding a VP or Declic? You have plenty of time to add higher, less classic styles.
Although I agree, all age comments aside IMO, I think 150mm is a huge jump from only 100mm, I personally wouldn't jump up that high so quickly despite the LP having a platform. I went from 120mm CLs to my 140mm Biancas and definitely felt the difference at first, the new height took some getting used to, even though I had some 140s in other brands, I was shocked!
I too was worried about 140s being too short, but honestly since getting them that's not the case, my Biancas clock in just short of 6 inches, and I don't feel like they look too short in my avi, if anything they look higher than I expected!
If you want a 140 heel I think the Bibi is an awesome choice for you and your lifestyle, they're gorgeous and they'll be more stable to walk in regardless of the height jump because of the thicker heel.
Yup, it's definitely a big jump, sweet pea, especially for your age.
(as stated above, not to offend babe!)
Go for the Bibi!!
might just go for the Bambou then. 
It is a big jump, obviously, but that doesn't necessarily mean you shouldn't make the jump!
Yeah the thing I love about the LP is how high the heel looks, when I tried on the Lady Clou the heel looked gorgeously high lol. I don't like being short
I'm short, too, girl. I think that Bambou would look lovely on you.
