I'm sorry, what? Have you actually read, for example Dr. No? Where Bond has a fight with a giant squid, and then escapes from Dr. No's complex using the dragon-disguised swamp buggy? Casino Royale (the novel) is probably the most grounded of Fleming's Bond novels; it is also by far the most boring and there's a reason that the Bond film franchise was launched with the far superior Dr. No (they actually wanted to launch it with Thunderball, which features shark pits etc., but there were writing disputes). Most of the rest of the Fleming bond novels are as outrageous as the films - from the very second Fleming novel, Live and Let Die, we have people being fed to sharks, people smuggling gold dubloons, a villain called Mr. BIG, and an evil villain organization named SMERSH. Hell, let's quote the Times Literary Review opinion of Live and Let Die: ""Mr. Fleming works often on the edge of flippancy, rather in the spirit of a highbrow", right back from its 1954 release. Besides, even if it was the case that novel Bond has a serious tone, which I heavily, heavily dispute, that's certainly not the case of the films, which have never been afraid to deviate from the novels in the first place, and have maintained their own tone.
You remind me of those bizarre people who insist that ASM is better than SM2 because Peter Parker is truer to the comic book version. Nobody gives a shit about the comic book version because ASM was terrible and SM2 wasn't.
SMERSH is a real thing.
And Live and Let Die, despite some flamboyant elements, isn't that ungrounded. I'd say that the first novel to really get to silly levels is Goldfinger and stealing all the gold in Fort Knox Pussy Galore, Jack Strap et al, that's quite a ways in.
You could make a case for Moonraker and the plot to nuke London, but the way it's handled it's that cartoonish.
