No, it can't. Tarski requires that True be a predicate, i.e, a truth
valued function of one term.
It does not matter a whit what the Hell his misconceptions
required.
It is not required by any misconception. It is required by the
meanings of the words and symbols, in particular "predicare"
and "~".
That none of modern logic can handle expressions
that are not truth bearers is their error and
short-coming.
Why should any logic permit formulas that are not truth-bearers?
(Of course, term expressions are not truth-bearers.)

Nope. And "expressions" are not "undecidable", but "Problems" are.

instance unless it is a part of that finite string expression.
That a specific problem instance is a single finite string expressionLike how to get your wife to quit yelling at you?
is true about formal problems but usually not about practical problems.
