I generated huge entropy because 256 bits of entropy didnt seem secure to me:   this is what 256 bits look like. 83926714dbf1948da358e3bddd99818d1b9fd3fd58c55e65765ffd780a4b4970   this is it. looks very breakable

You should try to avoid doing things that are not "standard" because if you are lucky the worst thing that could happen is that you will have a lot of problems recovering your funds by duplicating that self-defined process but if you are not you would be creating a weaker method that could endanger your funds.
Try to stick to the standard defined methods that are created by experts and are used by many implementations and their users.

It's like saying "how difficult is it to get to Pluto vs how difficult is it to get to Jupiter"... For all intents and purposes, they are both "impossible".

i know its way too much but how safe is it vs 24 word seed?

As mentioned above, having a 600 word seed just adds in unnecessary complexity and is more prone to errors in transcribing and/or more likely to become problematic when attempting to restore.

It was not generated using iancoleman tool. The maximum number of word it takes is 24 words, as you can see in the picture below
Possible, using custom entropy in the checkbox. The words will still be derived from the list.

@OP, the benefits of extra entropy diminishes with the increasing seed phrase length. 24 word seeds are already an overkill, 12 words is sufficient it provides for 128bits of entropy. It is far easier to have to type/store a 12 word seed than a 24 word seed and of course, 600 word seed. Most wallets do not support seed phrases that long and there is really no usecase for anything like that.

It is not safer. There is no need to use 2048^600 combinations. This is will be problematic for you to save and recover when needed.

What you might have done, is to use 24 word + 576 passphrase words. This will make your wallet unsafe, risky and you will probably lose your funds when you need to recover it.

WHen you add custom 576 words, a small typo may cause your wallet to be lost forever. As there are too many words, it will be almost impossible for you to determine what could have gone wrong, and those words are custom: They do not come from a fixed 2048 list of words.
