Lois did not commit any crimes, perfect or flawed in the November 1945 issue of Superman, although she did meet a modern Annie Oakley in May 1951 (Superman #70). She was featured in Mrs Superman (Superman #76) and wanted in Action #195, and had six lives in Action #198 and X-ray vision in Action #202. The stories listed in the Showcase tryouts and Lois's own magazine are real, so overall, there were three stories (the first three) that never existed, out of the fifteen.
And, oddly enough, that turns out to be pretty good as the next Lois Lane Annual had seven phony baloney stories:
The others ["Lois Lane's College Sweetheart" (Action Comics, March 1939); "Lois Lane on Krypton" (Superman, May, 1944); "Lois Lane's Super-Dream" (Superman, August, 1945); "Lois Lane in Smallville" (Superboy, July, 1945); "The Girl of Gold" (Action Comics, June, 1952); "When Lois Met Green Arrow" (Adventure Comics, December, 1952); and "The Luck of Lois, Lana and Lori!" (Showcase No. 8)] were invented for this list for reasons that will almost certainly remain unknown.Well, my guess is that Weisinger just didn't care if he got that list right; back then the assumption was that nobody would ever check this stuff. There are some pretty obvious problems with the above list: Superboy didn't have his own magazine until 1949, and Showcase #8 was a Flash issue, not a Lois Lane tryout.
