Su-25 design dates to 1968 and follows a proud tradition of survivable, anti-tank designs that go back to the Il-2 and beyond.
A-10 design dates to 1970 or so.
The Russians may well have copied concepts and designs, but they didn't copy the A-10 (or the concepts that it was built around) when they created the Su-25.
