Although your question has merit for this case specifically as ASML is a Dutch company there is very little hand wringing about outsourcing. For the forseeable future the Dutch are going to toe Washington’s line. In fact in some ways it’s desirable to throw middle powers a bone every now and then as it gives Washington an additional geopolitical bargaining chip that can be more easily called.

ASML's EUV light sources are made in San Diego (ex Cymer) and many of their EUV twin scan machines are made in Wilton, CT. So oddly it seems they outsource to the US.

Cymer seems to only do DUV light sources, the EUV stuff is developed by Trumpf and Zeis in Germany.

"ASML San Diego is responsible for the R&D and manufacturing of EUV light sources for lithography systems. Cymer focuses on DUV light sources." From ASML's website.

ASML San Diego was part of their joint research before acquisition.

afaik they bought Cymer specifically for the light sources, so it makes some sense.
