I expected it to look something like this:

exec spAddCaseToDeletedInso @Case, (select case when
dbo.getCaseOwnerByCaseId(@Case) = 1 then '3' else '2' end)

Your assumption is simply wrong. Check EXECUTE documentation

Execute a stored procedure or function
[ { EXEC | EXECUTE } ]
    { 
      [ @return_status = ]
      { module_name [ ;number ] | @module_name_var } 
        [ [ @parameter = ] { value 
                           | @variable [ OUTPUT ] 
                           | [ DEFAULT ] 
                           }
        ]
      [ ,...n ]
      [ WITH RECOMPILE ]
    }
[;]

As you see you can pass as @parameter:

• value
• @variable
• DEFAULT

So you need to use variable to hold result of function call and pass it to stored procedure.
