I would call that grammatically incorrect. "Existed" should be "existing" or "pre-existing". The word "of" is optional, and I would tend to leave it out.

I would say both "built off" and "built off of" are incorrect (or at least overly colloquial) and it should be "built on". The metaphor here is you are building something on top of another thing.
I see the same problem with "based off of"; it should be "based on" for the same reason.

I think that "Built On" or "Based On" are your best bets for the first two. "To Be Built Off Of" reflects (to me, at least) actual building. Exampl: The addition to the house was built off of the existing hallway.
As for the third one, it would sound absolutely normal in common speech. Especially when the secong "that" is emphasized.
I'm pretty sure that THAT idea was already mentioned.
I think for written English it would be better without the second "that". That is a tricky one, though. Good question.

2- Students should read already existed ideas and build off them.
3- I'm pretty sure that that idea was already mentioned.
I think I have to repeat "that" twice! |

1 - If there is a new idea, it should have been built on an existing one. (although in
everyday conversation, you will hear "built off" used instead of "built on")
2 - Students should read existing ideas and build on them. (In this case already is not
needed based on the definition of "existing")
3 - I'm pretty sure that idea has already been mentioned. (as the others have
mentioned, the first "that" is optional and usually left out).
Great questions.

I'm not familiar with "build off" or "build off of" expression so I looked it up on the
internet but haven't found it in any phrasal verb dictionary, but I came upon this

Putting aside the issue of "built off" v. "build on", etc, I think there is some mashing of verbal use in this sentence, but it is not entirely clear to me the proper resolution. It just strikes me as slightly incorrect. A mish-mash of present indicative ("if there IS a new idea...") with what seems to be a past subjunctive ("... it SHOULD HAVE BEEN built....").
Not entirely sure what I would suggest as an alternative. Perhaps:
If there were to be a new idea, it should be built...
