Is there any compact, mainstream notation for a function from all members of a tuple minus one? What I have in mind is
$f\left(a_{1},\ldots,a_{n}\right)$ (except for $a_{i}$) $=a_{i}$

If you mean an ordered tuple, then a common notation for $(a_1,a_2,\ldots,a_{i-1},a_{i+1},\ldots,a_n)$ is $(a_1,a_2,\ldots,\widehat{a_i},\ldots,a_n).$ But it is usually specified in text what it means the first time it is used.
I usually see this denoted $f(a_1,\ldots,\hat a_i,\ldots,a_n)$, with the $\hat\cdot$ sumbol used to denote exclusion.
