You think we should be concerned about our logo being used by Lego. If it should be concerning then what options you think we have?

... but if you think you could be ceding some copyright by allowing them to coincidentally use this meaningless pattern in a sample frame design in their product photo, then maybe you should mention it to Lego. I am sure they have nice lawyers.
Your thinking is a result of a toxic IP environment. Try not to make it worse.
There's no apparent trademark infringement here.
There is no confusion between your specific goods or services and those of The Lego Group, which is the purpose of trademarks.
Quoting https://www.uspto.gov/trademarks/basics/what-trademark :
> For example, let's say you use a logo as a trademark for your small woodworking business to identify and distinguish your goods or services from others in the woodworking field. This doesn't mean you can stop others from using a similar logo for non-woodworking related goods or services.
Your trademark (without the name or border) is weak. See https://www.uspto.gov/trademarks/basics/strong-trademarks for some background on what makes a strong trademark.
For example, even though I never did a graphical trademark search before, I found US trademark #90287353 as another example of using squares and "Triangles with one or more curved sides" as the interior of your logo does. It could also easily be done by the "Dots" toy.
Your entire trademark is a stronger one, but The Lego Group doesn't appear to be infringing on that one at all.
You could talk to a lawyer of course. But ... why? Let's say it costs only $1,000 to get Lego to change. Does it benefit you in any way?
I'm just confused, correct me if I'm wrong.
