As I understand, under Newtonian Gravity, there are no limits for the length of the gravitational influence of an object, except the speed of causality and the age of that object. So, considering the Sun as an example, which is roughly 4.6 billion years old, its gravitational influence would expand for 4.6 billion light-years.
Of course, that scenario considers the Sun just appeared out of nowhere. Considering the matter that originated the Sun was there before it became a star, the Sun gravitational influence would possibly expands to the whole Universe.
How that works under General Relativity? Considering the existence of Dark Energy, and any other stuff of GR meaningful to the question, would the limits of the gravitational influence of objects be different?
