I suggest using my IsSurvivorThirdPerson()
because that will catch most things that would stop you from throwing anything.

Here i modded it abit so you could use it here, i'm not 100% sure.

static bool:IsSurvivorThirdPerson(iClient) 
{
    if(GetEntPropEnt(iClient, Prop_Send, "m_isIncapacitated") > 0)
        return true;
    if(GetEntPropEnt(iClient, Prop_Send, "m_pummelAttacker") > 0)
        return true;
    if(GetEntPropEnt(iClient, Prop_Send, "m_carryAttacker") > 0)
        return true;
    if(GetEntPropEnt(iClient, Prop_Send, "m_pounceAttacker") > 0)
        return true;
    if(GetEntPropEnt(iClient, Prop_Send, "m_jockeyAttacker") > 0)
        return true; 
    if(GetEntProp(iClient, Prop_Send, "m_isHangingFromLedge") > 0)
        return true;
    if(GetEntPropEnt(iClient, Prop_Send, "m_reviveTarget") > 0)
        return true;  
    if(GetEntPropFloat(iClient, Prop_Send, "m_staggerTimer", 1) > -1.0)
        return true; 
    switch(GetEntProp(iClient, Prop_Send, "m_iCurrentUseAction"))
    {
        case 1:
        {
            static iTarget;
            iTarget = GetEntPropEnt(iClient, Prop_Send, "m_useActionTarget");
            
            if(iTarget == GetEntPropEnt(iClient, Prop_Send, "m_useActionOwner"))
                return true;
            else if(iTarget != iClient)
                return true;
        }
        case 4, 6, 7, 8, 9, 10:
            return true;
    }
    
    static String:sModel[31];
    GetEntPropString(iClient, Prop_Data, "m_ModelName", sModel, sizeof(sModel));

            }
        }
    }
    
    return false;
}

Also this has a check you missed
if(GetEntPropEnt(iClient, Prop_Send, "m_carryAttacker") > 0)
return true;

is missing from your IsInShape()
bool.

Be sure to convert to new syntax if you dislike my old syntax code.

enjoy

EXTRA:

GetEntPropEnt(client, Prop_Send, "m_tongueOwner") > 0

I don't use this because you can still throw stuff while is m_tongueOwner > 0
This will report back greater than 0 but you can still throw stuff, shoot and melee in the first second of being pulled, that is why i used sequences instead.

and

switch(GetEntProp(iClient, Prop_Send, "m_iCurrentUseAction"))

can be used for bot plugins Example "my bots use upgrade packs and other stuff", that would interfere with the bot plugins I use,
it's just a suggestion for compatibility with other plugins and more friendly to bots that are healing team mates
