Making noise for noise's sake?
At this stage, however, it’s important to note that this scenario remains hypothetical.

Netanyahu never announced any plans to attend the event  -- it is the Polish deputy foreign minister who floated the idea in a newspaper interview --  and it is unclear whether the prime minister would attend even if the ICC case weren’t a factor.  

The natural candidate to represent Israel at such a ceremony would be President Isaac Herzog.

Indeed, five years ago, a week after the event in Jerusalem, then-President Reuven Rivlin represented Israel at a 75th anniversary commemoration held at Auschwitz.

Herzog himself traveled to Poland two years ago to mark the 80th anniversary of the Warsaw Ghetto Uprising.

Israel’s ties with Poland have been tense over the last number of years, making Israeli representation at such events more complex.
