Problem Detail: So lets consider the following grammar $$ begin{align*} S &to 0 mid 0A A &to 1 end{align*} $$ would the string “1” be accepted by the language or must the language start with $S$?

No $1$ will not be a part of the grammar, as only those strings generated by starting from the start variable $S$ are part of the grammar.
