...I think one possibly solution would be to alter how some (not all) of these interactions work. Instead of automatically going to the dice roll, maybe having proficiency with a skill could sometimes be counted as an automatic success. Let's say giving us the option to bypass DCs that would be equal to or lesse than 8 + skill bonus if (and only if) we're proficient.
I agree, I think there are really to many dice rolls in regards to conversations etc. I mean 1 here or there is fine, but when you have to do a roll check like 2 or 3 times in a single conversation it gets annoying.
