Every time I see the word beginning from sumbol "l" I can’t tell whether it is "l" or "I"

The only font designers who care about clear distinction of symbols are those who create fonts for coders

Simple clarity test:

Il10O

All 5 chars should have clear distinction. Otherwise the font is shit.

often, you can clearly distinguish them from each other... but still don't know which is which.

though i admit, that its become pretty normal for the I to be smaller than the l and the O to be rounder than the 0.

I'd prefer that to be even clearer. I.e. a point in the Zero or rounding the ends of the small L
