There are things which are prohibited because they often lead to Lashon Harah. These are generally classified as the prohibitions of Avak Lashon Harah, such as talking excessively of someone's praises, or talking about someone (non-negatively) in front of someone who hates that person. So to answer your penultimate question, yes, you do have a certain degree of responsibility to prevent Lashon Harah.

However, mar'is ayin is not necessarily for that reason. It is sourced in the verse from Bamidbar 32:22

והייתם נקיים מהשם ומישראל

You shall be clean from Hashem and Israel

Some understand that mar'is ayin is to prevent others from being misled by your actions. If someone sees you doing something, they may come to assume it is permitted and follow suit (A case of this is found in Beitza 11b according to Rashi's explanation there s.v. התם).

Others understand that it is an independent requirement to not give off the impression that you are sinning, as every act of sin is a chillul Hashem, a desecration of Hashem's name, as it shows that His will is not being followed (implication of Rambam Yesodei HaTorah 5:11).
