Given a L2A product, is there a way to check which version of sen2cor (2.8.0; 2.5.5) were used to generate it?
You can check the processing baseline in the MTD_MSIL2A.xml file. Sen2Cor v 02.08 started with the processing baseline 02.12. But notice that the S2 PDGS is using more versions than the public sen2cor versions. For example, this is some of the sen2cor versions used in some processing baselines:

Around the line 70:
