Has to be with how tex works. The argument of any macro (\doifmode{mode}{...}
in this case) is scanned under the current catcode regime. So, any environment
(like typing) which changes catcodes does work inside the argument to another
macro.
So, either use the environment version of \doifmode (which doesn't _capture_ it
content):
\definetyping[T]
\definemode[mode][yes]
\starttext
\startmode[mode]
\startT
Bla
\stopT
\stopmode
\stoptext
Or use buffers (to avoid catcode all together):
\definetyping[T]
\definemode[mode][yes]
\starttext
\startbuffer[code]
\startT
Bla
\stopT
\stopbuffer
\doifmode{mode}{\getbuffer[code]}
\stoptext
or (note type**T**buffer so that the output is formatting according to the
options of \definetyping[T])
\definetyping[T]
\definemode[mode][yes]
\starttext
\startbuffer[code]
Bla
\stopbuffer
\doifmode{mode}{\typeTbuffer[code]}
\stoptext
Perhaps this should be added to the FAQ on the wiki.

[NTG-context] Typing within doifmode leads to error
Hi,
Consider the following MWE:
\definetyping[T]
\definemode[mode][yes]
\starttext
\doifmode{mode}{%
\startT
Bla
\stopT}
\stoptext
Compilation with the currently latest ConTeXt LMTX (ver: 2021.03.17 17:46
LMTX fmt: 2021.3.18) fails with:
tex error > runaway error: end of file encountered
mtx-context | fatal error: return code: 1
Compilation is successful if I replace doifmode{mode}{...} by
\startmode[mode]...\stopmode.
Is there anything I'm missing? (This could be a bug.)
Cheers,
Christoph Reller

The missing $ error is because the cases environment uses two column separators
(for the second column): \NC for "normal text column" and \MC for "math
column". This is so that in the typical case, you can just use:
\startformula
x = \startcases
\NC 1 \NC case $a_1$ \NR
\NC 2 \NC case $a_2$ \NR
\stopcases
\stopformula
So, in your cases, you should have used:
\starttext
\startformula
x=
\startcases[align={right,left},distance=3pt]
\NC a \MC =
\startcases[align={right,left},distance=3pt]
\NC 1 \NC case a1 \NR
\NC 2 \NC case a2 \NR
\stopcases
\NR
\NC b \MC =
\startcases[align={right,left},distance=3pt]
\NC 3 \NC case b3\NR
\NC 4 \NC case b4\NR
\stopcases
\NR
\stopcases
\stopformula
\stoptext
But, something goes wrong and that doesn't work either (with a different error
message). I suspect that something is not getting initialized correctly at
\startcases and will look into that.

So MP gets the macro and tries array access... I tried \expanded,
\numeric, and resolving the page numbers via \ref[page][id] at the
various code levels - unsuccessfully so far - and out of wit now.

Re: [NTG-context] Add items to list with arbitrary page number
That's neat Hans. Thanks. Especially didn't know about \writedatatolist.
What I want is basically to manually construct a toc entry, but in compliance
with the overall styling of the contents list.
So, I was hoping for something like this?
\writetolist[chapter][location=here,pagenumber=4]{5}{It's a test}
Maybe I'm missing an easier way to achieve this?
