How do I form a sentence of these patterns "X does not arise from Y", "X not
due to Y", "X not because of Y", "There are other reasons for X". Since
obviously I cannot simply slap ない onto から or ので to form an "anti-causal"
particle.

Would the below constructions work?:

  * Xの原因はYじゃない
  * Xの原因はYだけではない
  * Xの原因は他がある
  * XはYだからじゃない
  * XでもYはない
  * XとYは関係がない

Are there better options for this type of relationship between X and Y? Or do
more colloquial forms or set phrases exist for stating anti/non-cause? I'm not
sure if my constructions sound unnatural. The way I constructed those
statements feel quite literal to me.

I think that "Yと関係なく、Xは…" is a fairly common expression.

You could naturally said "Xの原因はYではなく、" but you would have to say what the real
reason is.

Xの原因はYとは限らない is maybe not bad either, to express that the reason of X is not
limited to Y.

Xの原因はYじゃない good, but very direct. You'll be asked "What is the reason of X
then?"  
Xの原因はYだけではない similarly, "then, what else?"  
Xの原因は他がある I would say "ほかに(いくつか)ある"  
XはYだからじゃない hum, not very correct as far as I can think about it  
XでもYはない idem  
XとYは関係がない you just say it's unrelated, yes.

Some grammar points you can have a look at are "に(も)関わらず" and "を問わず" which
basically mean "disregarding X" or "unrelated to X". But they do not reflect
anti-causality.

That's my best shot for now.

In the following, I assume that _X_ and _Y_ take the form of a sentence like
`僕が遅刻した`.

  * If you want to presuppose that _X_ and _Y_ both happened, and assert that the former is not due to the latter, then a simple expression is:

> _X_ のは _Y_ せいではない  
>  _Y_ せいで _X_ のではない

Some of your examples can also be used:

> _X_ 原因は _Y_ からではない  
>  _X_ のは _Y_ からではない  
>

  * If you want to presuppose that _X_ and _Y_ both happened, and assert that the former is not **only** due to the latter, then you can use your expressions:

> _X_ 原因は _Y_ からだけではない  
>  _X_ 原因は( _Y_ ことの)他にある [Corrected]

  * If you want to be neutral whether _X_ or _Y_ happened, and assert that they are not related, then 

> _X_ かどうかは _Y_ かどうかに依らない  
>  _X_ かどうかは _Y_ かどうかに依存しない [Academic]  
>  _X_ ことと _Y_ ことは無関係だ

you can also use your expression:

> _X_ ことと _Y_ ことは関係(が)ない
