This is foolish. Leblanc can tower dive like no other. She also needs kills to stay properly leveled because she will never equal other mids in farm. So keeping her at tower will prevent her from ganking other lanes when it turns out you've come prepared--meanwhile allowing her to push against you will simply result in towerdives for the kill--if you're vulnerable, and nonstop ganks on other lanes--if you're not.
Leblanc needs a late game buff. It's really as simple as that. The reason playing conservatively works so well against her is because she is beyond useless without snowballing. Even if she snowballs, she'll be weak in the late game. Give her a late game support role and we'll see her played some more.
