Since you know the key, you should probably call GraphLinksModel.findLinkDataForKey, then use the return value (which is link data) in a call to Diagram.findLinkForData.

findLinkDataForKey doesn’t exists on model or diagram

Typescript believes instances of Diagram.model to be plain Models, but you are using GraphLinksModel. You can cast the model by saying (this.diagram.model as go.GraphLinksModel).findLinkDataForKey. Or since you are using the model in more than one place in your function, you could say const model = this.diagram.model as go.GraphLinksModel; and then reuse it that way.
