The paladin, cleric with spells and a lot of fear immune monsters will just walk around you unfortunately.

In 3.5e you had ways to ignore those restrictions and immunities. 5e don't have the rules for it as it built differently from 3.5e(there is no real need for them in 5e).
I didn't say it would be a good option :P Playing a fully pacifist character is hard, playing a fully pacifist tank even moreso. If it's level 9, you could go Swashbuckler instead; it doesn't let you do much in a solo boss fight, but it can hold back a troublesome enemy while the party clears out the mooks, plus the skill use of a Rogue means you can hopefully find alternative ways to spend your turn than attacking.

Another option could be a Mastermind Rogue, especially with the UA Historian feat. Just spend your turns Helping two allies at once. I am especially fond of phrases like, "Follow the example of Kush-lan, the Eviscerator of the Third Century! Kick him in the crotch and run!"
